Remove obsolete and unsupported CSS properties specific to Internet Explorer #8897
Description
Problem Statement
EUI still sets some -ms-prefixed CSS properties that aren't necessary anymore and cause CSSStyleSheet.insertRule parsing errors. Since EUI doesn't support Internet Explorer or pre-chromium versions of Microsoft Edge, we should remove these CSS properties.
Proposed Solution
All -ms-prefixed CSS properties and Internet Explorer-specific hacks should be removed.
Use Case
This causes errors to be printed out in Kibana.
Value / Impact
There's no user impact, but this work would help clean up our code and reduce the number of console errors EUI causes.
Urgency
This was reported internally. Due to the number of error messages this generates and the low complexity of this work, we should prioritize this work.
Do alternatives or workarounds exist?
