When I try to test this locally, Kibana opens in Chrome just fine but in IE11 I get this (not sure if it's a Vega problem? I guess I need to try a clean master on IE11);

Expected ';'

We'll need to add this as a flex-grow: 0 for larger media queries though, because it ends up like this on small screens

vs what it supposed to do:

The problem I had in testing the PR was caused by this recent change;
#30628

@flash1293 is working on a fix for that

@snide Fix for the IE testing problem landed in master

[flash1293]

@LeeDr There might be another bug preventing this from getting tested in IE - #31288

[snide]

@cchaos I now apply it through the breakpoint you had set up. For mobile it expands as normal.

Can't check IE, but works in chrome and FF
