133564 - Tab navigation IMG href focus skips elements

Status: VERIFIED FIXED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Andy Edmonds]

When IMGs are used as link contents and hrefs are stacked together with no
separation, focus indication during tab key navigation skips the 2nd element,
4th element, etc.

This is seen on apple.com's navigation. This was reported as a complete lack of
focus feedback in bug 133535, but in the nightly referenced below some focus
feedback occurs.

Testcase coming.

WFM on the testcase, 2002 042403 on Windows 98.

Comment 3

[Andy Edmonds]

Hmm, could be a very recent fix, still busted on the RC1 W2k, rv:1.0rc1 -20020417

I still see the problem on Linux with latest trunk CVS build

Comment 5

[Nick Kocharhook]

This bug and bug 138015 have the same root cause. When you space out the hrefs,
both bugs gets fixed.

I've attached an expanded testcase. Just a little copy-n-paste action from the
earlier one. :-) Tab around in it, and notice that neither bug appears in either
of the spread out sections, while both bugs appear in the first, concatenated
section.

Bug 138015 should be marked as a duplicate of this bug, and this bug's summary
should be changed to something like "linked images without spaces interferes
with tab navigation".

This may have been fixed by my trunk checkin for bug 136495 (the symptoms sound
similar, anyway). Can someone try this on a trunk build from 4/27 or later?

Comment 8

[Nick Kocharhook]

I tried this on trunk build 042808 in Mac OS X, and you're right, it's fixed.
Good work!

WFM Win2k, Gecko/20020429

Not changing status to WFM in case there's some chance this can land in 1.0. 
The testcases fail in RC1.  Will re-check with RC2.

[Nick Kocharhook]

This bug is a duplicate of bug 136495. And that bug is checked in on both the
trunk and the 1.0 branch.

Comment 11

[Aaron Leventhal]

this should have been marked fixed.

using 2002.09.19.08 trunk builds, this is fixed on win2k. tested with attachment
76237 and at http://apple.com.

however, this does not work on mac os 10.1.5 or linux rh7.2.

reopening. but if the mac and linux issue is already covered by a more recent
bug, do re-resolve this and point me to that other bug. thanks!

Comment 13

[sairuh (rarely reading bugmail)]

oops, pilot error. re-resolving: remembered that bug 140612 was fixed, so
tabbing to links is off by default on mac and linux.

Comment 14

[sairuh (rarely reading bugmail)]

related (but doesn't block this): bug 171003, where you need to tab twice to
move beyond a linked image.

Comment 15

[sairuh (rarely reading bugmail)]

vrfy'd fixed with 2002.10.15.08 comm trunk builds.
