I'm using the autocomplete textbox element in a Firefox extension, and I have the showcommentcolumn attribute set to true. As a result, two columns appear in the autocomplete output results. Unfortunately, the width of the second column is too wide. This is a direct result of these tree columns both having the attribute flex="1" set.
I should mention that the setter method for the showCommentColumn property down in the autocomplete-result-popup binding seems to do what I want: (see its source here). When the property is set, the column should have its flex attribute set to 2. In my case, however, this doesn't seem to happen. The XBL binding on my textbox control is pointing to the right thing, but that code doesn't seem to alter things.
Is there a simple way I can alter the flex attribute for the first column to be flex="2"? Unfortunately, these are anonymous content nodes, and I'm not sure how best to alter them (or if it's even possible). I'd rather not roll my own autocomplete search box to fix this one nit. Is there an easy way to alter the attributes of an anonymous node?
