Some software, like GoToSocial, expose replies as ActivityPub
Collections, but do not expose any item array directly in the object,
causing validation to fail via the ObjectID validator. Now, Pleroma will
drop that field in this situation too.
The (request-target) used by Pleroma is non-standard, but many HTTP
signature implementations do it this way due to a misinterpretation of
the draft 06 of HTTP signatures: "path" was interpreted as not having
the query, though later examples show that it must be the absolute path
with the query part of the URL as well.
This behavior is kept to make sure most software (Pleroma itself,
Mastodon, and probably others) do not break, but Pleroma now accepts
signatures for a (request-target) containing the query, as expected by
many HTTP signature libraries, and clarified in the draft 11 of HTTP
signatures.
Additionally, the new draft renamed (request-target) to @request-target.
We now support both for incoming requests' signatures.
This implements fully_qualify_emoji/1, which will return the
fully-qualified version of an emoji if it knows of one, or return the
emoji unmodified if not.
This code generates combinations per emoji: for each FE0F, all possible
combinations of the character being removed or staying will be
generated. This is made as an attempt to find all partially-qualified
and unqualified versions of a fully-qualified emoji.
I have found *no cases* for which this would be a problem, after
browsing the entire emoji list in emoji-test.txt. This is safe, and,
sadly, most likely the sanest too.
Tries fully-qualifying emoji when receiving them, by adding the emoji
variation sequence to the received reaction emoji.
This issue arises when other instance software, such as Misskey, tries
reacting with emoji that have unqualified or minimally qualified
variants, like a red heart. Pleroma only accepts fully qualified emoji
in emoji reactions, and refused those emoji. Now, Pleroma will attempt
to properly qualify them first, and reject them if checks still fail.

How it fails?

> so if we get 2 clears too close together, maybe it locks, then doesn't like the next clear?
