Currently, a 'display: block' element inside a sticky 'display: inline' element will *not* stick in Chrome, but will in Firefox. Other contents of the sticky 'display: inline' element will stick (e.g. text).

Not checked Safari yet. Edge has no sticky support yet.

Need to check the spec to make sure which is the correct behavior here.
