Compatibility View Settings in IE

[lexjansen]

Comment from a user: "We at [...] were struggling because we couldn't collapse the VLM. We finally discovered that it was because in the Compatibility View Settings option in the IE Tools menu, "Display intranet sites in Compatibility View" option was ticked. When I unticked that, then collapse/expand worked. After some research, I discovered that I didn't have to worry about that option if I inserted a new Meta tag - meta http-equiv="X-UA-Compatible" content="IE=edge". I added this line to the new stylesheet and didn't have the problem any more."

Is this related: IE8 won't load JavaScript file in “Compatibility View.” ?

I checked define.xml + stylesheet with Inspector in Firefox 84.0.1 (64-bit), and on initial load, there are 4 warnings:

1.Unknown property ‘-moz-border-radius’.  Declaration dropped.
2. Unknown property ‘-moz-box-shadow’.  Declaration dropped.
3. Error in parsing value for ‘padding-left’.  Declaration dropped.
    Elements matching selector: ul.SubClass
4. Expected declaration but found ‘#000000’.  Skipped to next declaration.
    Elements matching selector: .arm-summary-resultdisplay

However, the expand/collapse vlm buttons work as expected.

Would it be better to have only one button to toggle "expand/collapse vlm"?

I do not believe one button would solve the issue.
