* DEV: Remove the margin from widget-dropdown
Generic components should not have a margin. Those should be styled in the place where they are used.
* DEV: Remove margin from the dropdown body
It triggered a warning in popper and was effectively a no-op as popper positions dropdowns on its own using `position: fixed` and `top/right/bottom/left` properties.
Newer versions of Normalize remove the `border-collapse: collapse;` property and fallback to browser defaults. This commit restores that property because we're using it in quite a few places.
The admin permalink list was a little tricky to use because the URLs are easily reduced with a ... if they are too long. This adds a copy to clipboard button for the URL and a title on hover so the full text of the URL can be seen.
* FEATURE: Don't display muted/ignored users under "who liked"
Previously, if you clicked on the heart icon below a post
it would show you the avatar for a user even if you ignored or muted
them.
This commit will instead display a (?) icon. The count of likes will
remain correct, but you needn't be reminded of the person you
preferred not to see.
* Use a circle instead of (?) for unknown user
It's a stop gap – ideally we would generate a thumbnail for uploaded videos. For now, a bit of intentionality in the style and a pinch of context should do.
* Fixes position of the top arrow, and border width of both
* Merged top and transform properties
* .5px values are required to make arrow border appear the same with as overall popover border width
I did have a chance to try it out on a Windows machine with a non-high DPI display and there were no issues. And I just re-tested it with Firefox on macOS using the "Open in Low Resolution" option and it looked more or less ok (bearing in mind that it the whole app is then a blurry mess, and that using custom zoom levels causes the arrow to break slightly, but that was also the case on Firefox before this change)
