The current web UI (master, but stable14 had similar issues) looks not that good in Edge:

@skjnldsv so grid view doesn鈥檛 work in Edge either? Should we also do the "Only list view" fix there?
@jancborchardt nope, edge is really decent on feature support. I'm guessing something needs a fix, but it should be ok :)
Looks fine to me. We shall call it the windows experience :)
Works fine on latest edge :thinking:

The only issue I could find is the arrow on the popover now showing because of this bug: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/17410857/ where the ::after inherit from the parent (bad!) and therefore the border attributes are overrided and thrown away.
@MorrisJobke any updates?
I just used a never version of Edge (mine was from early 2017) and this issue is gone.
