impossible to find out

@Elchi3 this sounds like an argument for removing the feature (or removing the feature, but stuffing the existing data into an issue and hope someone comes along and cares enough to figure out what the story is)

[Elchi3]

I agree! If we can't get info on this one in the next few days, we should drop the data.

[Elchi3]

Only 5 left!

[ddbeck]

Only one feature remains! But, of course, it's a doozy: css.properties.position.position_absolute_table_elements. I haven't been able to figure out what to do about it.

#607 (review) explains how the feature came to be in our data in the first place (though it used to have a slightly different name, see #872 for that).

At one time, the behavior of position: relative with table elements was undefined, but it was later defined in CSS Positioned Layout Module Level 3. Reading bug 35168, it looks like the problem was that Firefox had a different behavior from the other browsers (which could've been legitimately anything, thanks to the spec saying the behavior is undefined), but I'm not 100% sure about that.

[Elchi3]

Trying my luck paging @chrisdavidmills and @teoli2003 to shed some light on this story.

[Elchi3]

I've decided to make this a note in #4689. It is not worth investing tons of time into this.

[Elchi3]

This is done now! cries tears of joy

[ddbeck]

Hooray!
