Bug 11965 – REGRESSION: 1 pixel on left/right inside of focus ring is erased while typing

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[David Kilzer (:ddkilzer)]

Summary:

When typing in a textarea that has lost and regained focus once, typing causes 1 pixel of the focus ring to be erased on the left and right inside border.

Steps to reproduce:

1. Open the URL above.
2. Put focus in textarea.
3. Type "asdf".
4. Tab out of the textarea.
5. Shift-tab into the textarea.
6. Type one more character, or delete one character.

Expected results:

The left/right inside focus ring should not lose 1 pixel of its border.

Actual results:

The left/right inside focus ring loses 1 pixel of its border.

Regression:

This is a regression from shipping Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).

Notes:

May be related to Bug 9569.  Bug 8268 is similar, but affects the top/bottom border and is caused by the caret.

Screenshot of text input

This screenshot shows this isn't limited to just textareas, but text inputs also.

<input type="text" style="border: 1px solid black;"> is the code from the screenshot.

Actually that's Bug 8268.

This is most likely the same problem as bug 8268. See the comments there.

I can no longer reproduce this.  Can someone else confirm?

(but I can still repro bug 8268)

I can still reproduce (using 10.4.9 here).

I cannot reproduce this with r28320 on Tiger (note that this is before Adele's patch for <rdar://problem/5499918>.

I don't see this anymore with a local debug build of WebKit r28434 with Safari 3.0.4 (523.12) on Mac OS X 10.4.11 (8S165).

Actually, it looks like the "inner" 1-pixel-wide ring of light blue shading is gone with the above configuration.

Marking as RESOLVED/FIXED.

Note that I can still reproduce Bug 8268.
