Comment (by kevin940726):

 @musicaljoeker Unfortunately, just updating `z-index` of `#adminmenuwrap`
 to `1000001` will cause another side effect shown in the attachment above.

 IMHO, I think this is currently not solvable, at it seems to be in a
 bigger scope than we thought.

 The [https://developer.mozilla.org/en-
 US/docs/Web/CSS/CSS_Positioning/Understanding_z_index/The_stacking_context
 stacking context] of the page is roughly like this:

 {{{
 Body
   #adminmenuwrap
     .wp-submenu-wrap
   .components-popover
 }}}

 So, we cannot make `.components-popover` show between `#adminmenuwrap` and
 `.wp-submenu-wrap`. The only option I can see is to "portal" the
 popovers/submenu to desired location and control their positioning with
 JavaScript somehow, and that's a huge amount of work.

 However, we might could get an update to the side bar after
 [https://core.trac.wordpress.org/ticket/47012 47012] landed, and
 hopefully, we could solve this issue once and for all.
