Compound (ZWJ) emoji does not work

[BobVul]

Description

It's not possible to use ZWJ emoji (see also) at the moment. Much of the emoji inserted by the Windows 10 emoji keyboard (Win+; or Win+. on version 1803) uses ZWJ sequences.

These work in most other text entry fields in the same browser, e.g. this GitHub comment box.

Steps to reproduce

• Copy one of the gendered shrugs into the input field: 🤷‍♂️ or 🤷‍♀️
• Type a space after to get the field to process the character

Alternatively:

• On Windows 10 v1803, press Win+; or Win+. to bring up the emoji keyboard
• Search for shrug and enter one.

The glyph is not a single male or female shrug as expected, but an ungendered shrug with a male or female symbol afterwards.

There is also an extra glyph appearing in the input field, #7347

Emojione only has support for that starting from version 3 (which is unusable due to licensing), so this would most likely fixed by switching the emoji pack (#7354) and/or allowing native emoji (#7356)

Yeah, I'll leave this issue here to track this specific problem, but we'll most likely fix this by finding a more up-to-date replacement for emoji one (with a compatible license)

Closing because we're removing emojione (#9281) - we can revisit this if it becomes a problem post-removal.
