Bug 11022 – queryCommandState('underline') returns false if the selected text is also bold and italic

• Status: RESOLVED
• Resolution: FIXED
• Component: HTML Editing

[Chris Petersen]

* SUMMARY
Inserting a caret into styled text (bold, italic, underline) doesn't highlight the associated toolbar buttons (bold, italic, underline)

* STEPS TO REPRODUCE
1. With TOT Webkit r-16541 , login to your gmail account
2. Create a new message  (Rich Formatting)
3. Place caret in message body and and click "B", "I" and "U" . Notice the button are highlighted when pressed.
4. Type out "This is some text". Verify this text has all three styles applied.
5. With this caret at the end of this text, press the return to create a new line
6. Place the caret at the end of  "This is some text" and press the return key. This will place the caret on a new line.
7. Click "B", "I", and "U" to remove this style then start to type some text
8. Now, click in the line above which contains styling on the text. Notice , the B, U, I buttons don't become highlighted.

* RESULTS
Style buttons on the toolbar should become highlighted if caret is inserted into style text but isn't.

Looks like it's fixed for bold and italic.  Still broken for underline, though.

Underline seems to only have problems when the text has is also Bold and Italic.

This bug is caused by us checking text-decoration property.  We should be checking -webkit-text-decorations-in-effect.  It's literally two-line change for underline and line-through.  I'll submit a patch after writing some tests.

This is a little mysterious. Usually "ditto" means "repeat the comment above". In this case the only comment above is the summary one describing the entire change. I'd suggest writing something other than "ditto" here in patches in the future.

I would have written:

        (WebCore::stateStrikethrough): Use -webkit-test-decorations-in-effect instead of text-decoration.
        (WebCore::stateUnderline): Ditto.
