164840 - Colour sticks when setting *.style.background via JavaScript [inline]

Status: VERIFIED WORKSFORME

(Core :: CSS Parsing and Computation, defect)

I wrote a JavaScript function that toggles the background colour of table cells
on mouseover / mouseout of images and links by setting a colour value to
*.style.background, however, it doesn't work as expected.

On first mouseover the colour changes, sticks and doesn't reset on mouseout.
Only after you mouseover again, does it begin to work properly.

(Plus, when I was using an image with transparency, the background colour wasn't
rendering to the full width of the cell on first mouseover.)

It works fine when you set *.style.backgroundColor instead.

To tables...   I see this on Linux too.

Seems more like a style system bug to me.

This seems to be fixed by the patch in bug 171830

Please retest with tomorrow's build (I cannot reproduce this in a current
nightly without the patch for bug 171830 even, so....)
