Fixes #11767. Previously multi-character emoji sequences weren't matched in the emoji regex, so we'd convert the characters to separate images, breaking the intended display. This change allows us to match the full emoji sequence, and therefore show the correct image.

# Starting from version 4.0.0, `emoji_datasource` package has started to
|
|
# add an emoji presentation variation selector for certain emojis which
|
|
# have defined variation sequences. The emoji presentation selector
|
|
# "qualifies" an emoji, and an "unqualified" version of an emoji does
|
|
# not have an emoji presentation selector.

|
# Since in informal environments(like texting and chat), it is more
|
|
# appropriate for an emoji to have a colorful display so until emoji
|
|
# characters have a text presentation selector, it should have a
|
|
# colorful display. Hence we can continue using emoji characters
|
|
# without appending emoji presentation selector.
