 > If this is the main discussion - I'm almost certain the issue lies with
 the tooltips JS. Removing the tooltips implementation seems to fix the
 issue but that is certainly not a possible solution.

 Yes it is and it's related to scrollbar. Adding:

 {{{
 html {
     overflow-y:scroll
 }
 }}}

 solves this issue as described here
 https://github.com/WordPress/Gutenberg/issues/14878

 Probably there is a problem with cached width or something that triggers
 some action that cause flickering.
