I'm finding weird behavior where on the main /tags page, hovering
over the tags shows the delete / unlink button without a problem,
but on a specific tag page hovering over this button causes the
rest of the list to shift a pixel or two.
I'm sure this line-height fix is nothing more than a bandaid and
not the right thing to change.
I think my original reason for doing this was to prevent the button
from being operational until after the spinner initialization has
completed, so you don't get any weird half-functional spinner buttons.
However, in practice I'm finding that I constantly forget about this
and it adds tedium to creating spinner buttons.
Will review if any actual problems come up.
Unfortunately these cards are taller rather than wider so the
already-neglected unlink buttom becomes even more horizontally crammed.
That's going to need a big fixup anyway.
The two-sided margin was meant to create a particular spacing on the
albums page, but the purpose of cards is I should be able to use
them in many other contexts. So an all-round margin is easier to
work with when displaying cards anywhere else.
On the main tag listing, for child tags, you only get an unlink
button on hover. So if you want to delete a child tag you'd have to
unlink, then refresh, then delete. Now you can just go to its page
and delete it there.
This hook had a bug where you couldn't select text because every
time you push a button, including ctrl+a or shift+left/right, the
cursor position gets reset and then deselects immediately.
So let's only reset the content and cursor only when text changes,
so arrow keys and ctrl don't have any negative effects.
Unfortunately, when adjusting the box's value, it causes the datalist
to disappear, and it only comes back after you press another key.
I can't figure out how to make the datalist reappear automatically
with js.
