677104 - Ctrl-arrow-right key can't move past text inside div inside span

Status: REOPENED

(Core :: DOM: Selection, defect)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, steps to reproduce:
- Press the ctrl-alt-right arrow key a couple of times

Expected result:
- The caret should move a word to the right every time the ctrl-alt-right arrow key is pressed.

Actual result:
- The caret gets stuck at the yellow block.

This regressed between 2009-03-04 and 2009-03-05:

Regression from bug 480323?

As a sidenote, I noticed that double-clicking on the first 'text' selects the first two 'text' words in current builds. This seems to have regressed somewhere in 2007.

Boris, this might be a regression from your patch in bug 480323.

Comment 2

[Boris Zbarsky [:bzbarsky]]

It's possible, yes.

If you add some text between the </div> and the </span>, does that make the problem go away?

Comment 3

[Martijn Wargers (dead)]

Yes, that makes the problem go away.

Comment 4

[Boris Zbarsky [:bzbarsky]]

Hmm.  What about this testcase:

  <span>Some text</span>
  <div>A block</div>
  <span></span>

Does that get stuck the same way?

(I'm asking the questions because the shortcut listed in comment 0 does something totally unrelated to caret movement for me on Mac, and I'm not sure what it's suposed to do with the caret, so can't really reproduce the bug.)

The option right arrow key seems to do the same on Mac as what the ctrl right arrow key is doing on Windows.
Except on the Mac, the layout.word_select.eat_space_to_next_word pref is set to false by default, while it is true by default on Windows.
That seems to cause a huge difference in behavior on the testcase. I'm not sure what the correct behavior would be in that case.

No.

With the original testcase, btw, IE9 puts the character at the end of the line, then on the start of the new line. Perhaps Mozilla should be doing something like that?
Anyway, at least, it shouldn't get you stuck somewhere.
