Styling Issues with asset admin on ie11

Silverstripe Version: 4.2.4

Hi, while testing a project in IE11 (via vitualbox), i’ve found that asset admin has very unusual styling issues.
I’ve tried everything i could think of to fix these in the inspector, but none of what i’ve tried has worked.

  1. selecting/deselecting any folders causes the main cms area to shrink to half width - I’ve been able to fix this temporarily, yet re-ticking or unticking a folder re-breaks it, regardless of what css i set
  2. the edit and delete buttons on the bottom are overlapping and i can only seem to fix it by removing flex styling
