I experience this as well, on VW.org XF wiki site (in threads, not profile posts), as well as my offline wiki test site. I
do not experience this on my second XF2.1 test site (which does not run VaultWiki).
Comparing both test sites, the one with VW enabled has additional CSS applied to the following element:
Code:
<div class="fr-box bbWrapper fr-ltr fr-basic fr-top" role="application">
The CSS is:
Code:
.bbWrapper {
overflow: hidden;
position: relative;
}
Froala drop-down menus are also cut off, e.g. Insert.
Seems that
overflow:hidden; could be the problem? Based on deselecting this rule in the browser inspector.
Edit: To clarify... my non-VW test site does not apply the above .bbWrapper CSS to the fr-box element, but the VW-enabled test site does.
Edit 2: I've traced this back to vw_bbcode.less. Temporarily commenting out the last section of this XenForo template stops the editor bug in this issue report.
