Fix jumping of toot date when clicking spoiler button

[ariasuni]

Fix the weird behavior you can see in this gif:

The date of the toot moves 2px down and up uselessly when clicking the spoiler button.

This 2px margin was introduced by you in #10821
So the fix would probably be to somehow add that 2px margin when the toot is hidden as well

I do not have the issue with the cut letters anymore, and I felt weird about adding a margin for that in the first place.

Can you confirm that letters aren’t cut anymore with:

.reply-indicator__content p:last-child, .status__content p:last-child {
    margin-bottom: 0;
}

and that my previous workaround is not necessary anymore?

I'm indeed unable to reproduce the issue fixed by #10821 without that rule, hmm
