The messages "X" close button are not visible in IE11 high contrast mode.
This is visible at https://tugboat-aqrmztryfqsezpvnghut1cszck2wwasr.tugboat.qa/message
We need to also test out the solution in high contrast mode on IE11, Edge, and Firefox.

mherchelCrediting @javi-er who found this bug

mherchelPatch attached.
The issue occurred because Windows High Contrast mode removes all background colors (and the close button was styled with a background color). The new patch uses borders.

lauriiiCommitted 87d16e4 and pushed to 9.3.x. Also cherry-picked to 9.2.x because Olivero is experimental. Thanks!
