The test fails on Fedora 28 by design, so just remove it.

• bpo-33975 [https://bugs.python.org/issue?@action=redirect&bpo=33975]: Avoid small type when running htests. Since part of the purpose of human-viewed tests is to determine that widgets look right, it is important that they look the same for testing as when running IDLE.

• bpo-33905 [https://bugs.python.org/issue?@action=redirect&bpo=33905]: Add test for idlelib.stackview.StackBrowser.

• bpo-33924 [https://bugs.python.org/issue?@action=redirect&bpo=33924]: Change mainmenu.menudefs key 'windows' to 'window'. Every other menudef key is lowercase version of main menu entry.

• bpo-33656 [https://bugs.python.org/issue?@action=redirect&bpo=33656]: On Windows, add API call saying that tk scales for DPI. On Windows 8.1+ or 10, with DPI compatibility properties of the Python binary unchanged, and a monitor resolution greater than 96 DPI, this should make text and lines sharper. It should otherwise have no effect.

• bpo-33768 [https://bugs.python.org/issue?@action=redirect&bpo=33768]: Clicking on a context line moves that line to the top of the editor window.

• bpo-33763 [https://bugs.python.org/issue?@action=redirect&bpo=33763]: IDLE: Use readonly text widget for code context instead of label widget.

• bpo-33664 [https://bugs.python.org/issue?@action=redirect&bpo=33664]: Scroll IDLE editor text by lines. Previously, the mouse wheel and scrollbar slider moved text by a fixed number of pixels, resulting in partial lines at the top of the editor box. The change also applies to the shell and grep output windows, but not to readonly text views.

• bpo-33679 [https://bugs.python.org/issue?@action=redirect&bpo=33679]: Enable theme-specific color configuration for Code Context. Use the Highlights tab to see the setting for builtin themes or add settings to custom themes.

• bpo-33642 [https://bugs.python.org/issue?@action=redirect&bpo=33642]: Display up to maxlines non-blank lines for Code Context. If there is no current context, show a single blank line.

• bpo-21474 [https://bugs.python.org/issue?@action=redirect&bpo=21474]: Update word/identifier definition from ascii to unicode. In text and entry boxes, this affects selection by double-click, movement left/right by control-left/right, and deletion left/right by control-BACKSPACE/DEL.

• bpo-33204 [https://bugs.python.org/issue?@action=redirect&bpo=33204]: IDLE: consistently color invalid string prefixes. A 'u' string prefix cannot be paired with either 'r' or 'f'. Consistently color as much of the prefix, starting at the right, as is valid. Revise and extend colorizer test.

• bpo-32984 [https://bugs.python.org/issue?@action=redirect&bpo=32984]: Set __file__ while running a startup file. Like Python, IDLE optionally runs one startup file in the Shell window before presenting the first interactive input prompt. For IDLE, -s runs a file named in environmental variable IDLESTARTUP or PYTHONSTARTUP; -r file runs file. Python sets __file__ to the startup file name before running the file and unsets it before the first prompt. IDLE now does the same when run normally, without the -n option.

• bpo-32940 [https://bugs.python.org/issue?@action=redirect&bpo=32940]: Simplify and rename StringTranslatePseudoMapping in pyparse.

• bpo-32837 [https://bugs.python.org/issue?@action=redirect&bpo=32837]: Using the system and place-dependent default encoding for open() is a bad idea for IDLE's system and location-independent files.

• bpo-32826 [https://bugs.python.org/issue?@action=redirect&bpo=32826]: Add "encoding=utf-8" to open() in IDLE's test_help_about. GUI test test_file_buttons() only looks at initial ascii-only lines, but failed on systems where open() defaults to 'ascii' because readline() internally reads and decodes far enough ahead to encounter a nonascii character in CREDITS.txt.

• bpo-32831 [https://bugs.python.org/issue?@action=redirect&bpo=32831]: Add docstrings and tests for codecontext.

• bpo-32765 [https://bugs.python.org/issue?@action=redirect&bpo=32765]: Update configdialog General tab docstring to add new widgets to the widget list.
