Changes (by SergeyBiryukov):

 * milestone:  5.5 => Future Release


Comment:

 Some relevant `z-index` numbers:
 * Admin menu: `#adminmenu .wp-submenu { z-index: 9999; }`
 * Link modal in block editor: `.components-popover { z-index: 1000000; }`
 * Link modal in classic editor: `div.mce-inline-toolbar-grp { z-index:
 100100; }`

 At a glance, bumping `#adminmenu .wp-submenu` to 1000001 should fix this,
 but needs a careful investigation of possible side effects. Moving to a
 future release for now.
