error message tooltip are truncated

Reproducible: Always

Steps to Reproduce:
1. open
2. click "go" button
3. see the tooltip
Actual Results:  
error message tooltip for <select> is truncated

Expected Results:  
tooltip width should not be linked to its field width

The tooltip width is linked to the <select> width minus the "open dropdown button".
I can reproduce this on Mozilla/5.0 (Windows NT 6.0; rv:2.2a1pre) Gecko/20110404 Firefox/4.2a1pre ID:20110404030429
I can reproduce the issue on:
Mozilla/5.0 (Windows NT 6.1; rv:2.2a1pre) Gecko/20110404 Firefox/4.2a1pre

But it's unclear whether this is a bug or not, as the error message tooltip is truncated in other browsers, as well.

It only happens with select elements: the popup size depends on the select element layout size.

as i said ;)
BTW, according to the regression window [1], it is very likely that bug 595432 triggered this one. IOW, it might be related to how arrow panels work.

Same problem on both Firefox 5 and 6:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0) Gecko/20100101 Firefox/6.0
Mozilla/5.0 (Windows NT 6.1; rv:5.0) Gecko/20100101 Firefox/5.0

The tooltips don't just get truncated, though. Here's a fork of the reporter's example with the width of the <select> set to 1000px:
Notice how the border of the tooltip expands with the width of the <select>.

Does one of you knows off-hand what could cause this?

With bug 672254 fixed, the issue is less major because it's no longer truncated but the tooltip is really small thus very high, which is annoying to read.

This is particularly annoying with very narrow select lists with one or characters in the option, such as a credit card month/year or such.  simple demo that is totally unreadable.

I can't believe this bug has existed for years with no workaround.  Surely there must be some solution in the browser CSS? An "overflow: visible" ?  Changing where the label is attached?

BTW, haven't looked at how the validation error message positioning is done, but the message does not move when scrolling - it jump suddenly once scrolling stops.  A bit odd, like how javascript based positioning used to work before people moved to CSS.
Oh, and if anyone has a less-insane workaround than the one proposed in:
using wrapping or making the select element really wide, I'm all ears.

Right now all I can think of, is disabling HTML5 validation on select lists below a certain width. (For Firefox only of course)
I think this happens because nsMenuFrame::IsSizedToPopup returns true when the anchor content is a <select>. That doesn't make sense any more. It probably made sense when nsMenuFrame was being used experimentally to draw the dropdown list for a <select> combobox, as it was when this code was added in 2002 in bug 128947.
