So I'm making a few adjustments here for our next XenBase release. Essentially XF hard codes a lot of font-size: 10px, 11px into the default style, in places we don't normally change. This should be a little more consistent on the next version, it was definitely more noticeable on Edge which uses larger font sizes.
Actually this next XenBase won't rely on XF release date, it's a larger release I'm close to pushing out. We normally ship with XF updates but I'm not sure when that will come with the 2.0 being the main focus.
Shouldn't be too much longer now and all these pesky edge issues will be fixed along with numerous improvements to the framework.
Awesome ... Most likely you have already seen, still just in case, want to point to another bug I reported in the customer support section (I actually didn't realize that was a bug, thought as per design. But @Steve confirmed it was a bug). Would be nice if you fix that as well in the next release, if not too much to ask.
