Define z-index on the new admin bar

[BlueKachina]

Proposal for z-index to be defined on the new admin bar (so that it will work in harmony with browser toolbar --> Web Develoepr Toolbar's "Display Element Information" Feature)

When the new admin toolbar is showing,
crucial information from the Web Developer Toolbar's
"Display Element Information" balloon becomes hidden.

Specifying a z-index for the admin toolbar seems to resolve this problem.

ie.
I changed line 92 of class-wp-admin-bar.php,
FROM:

<div id="wpadminbar">

TO:

<div id="wpadminbar" style="z-index:1000;">

It seems that the z-index value is somewhat arbitrary to getting these two toolbars to work in harmony... as I've tried values ranging from 0 to 1000, and they all worked.

Comparing before and after code modifications

We currently have z-index: 99999;. I imagine the toolbar uses a value of 100 or so.

Just did some more testing... it seems that the highest z-index I previously tested is the highest value that works with the Web Developer Toolbar's yellow balloon. I just tried z-index:1001; and the yellow balloon then appears behind the admin toolbar.

Looks like any value above 1000 renders the admin toolbar incompatible with the web developer toolbar.

How do you suggest we proceed?
How important is it that the z-index be kept at 99999 for the admin toolbar?

According to ​this, most browsers can handle much larger z-indices (and no maximum is determined by the standard), so it seems like Web Developer Toolbar bears the responsibility to fix this.

[BlueKachina]

Fair enough.
I've sent a message to the developer of it with the request to increase it above 99999, or to provide an option to specify one.

Seems like things like the toolkit and other bookmarklets should attempt a highest z-index as possible. Maybe we could tame ours a bit (say, 9999 rather than ten times that), but 1000 is too low.

Best I'm aware, 99999 isn't valid CSS, or supported by all browsers if it is. If memory serves -9999 to 9999 is the range that works everywhere.

Replying to Denis-de-Bernardy:

Best I'm aware, 99999 isn't valid CSS, or supported by all browsers if it is. If memory serves -9999 to 9999 is the range that works everywhere.

The CSS 2.1 spec ​doesn't seem to say what the max is.

For experiments on browsers' handling of them, please see the link in my previous comment.

Edited ticket title so it would stop messing with Trac layout in lists.

99999 seems like a perfectly valid value.
