Rules followed:
1. Bold and highlighted background if the mention was processed
as a mention that includes you.
2. Bold personal mention (but not highlighted) if you were mentioned
but not subscribed at the time.
3. Otherwise not bold, no highlighting.
As we plan to keep the mention pill CSS the same if a user
was mentioned via that personal/wildcard/usergroup mention
irrespective of whether the user is subscribed or not, we use
usermessage flags to determine when to add 'user-mention-me' class.
Fixes#27654.
This commit adds "(guest)" indicator to user names of guests
in mention pill if the enable_guest_user_indicator setting is
enabled for the organization. Note that the actual message
content does not include the indicator.
`copy code` button now show a `Copied!` tooltip when clicked.
It implements a similar function used on `saved as draft` notice.
We need to modify the copy_code_button template to limit
data-tippy-trigger to not include click; otherwise, repeated clicks to
copy code will incorrectly also display the "Copy code" tooltip
alternating with "Copied".
Fixes part of #21036.
Implemented date localization using native Intl object.
Created special function get_localized_date_or_time_for_format
Made necessary string formatting changes in 'timerender.ts'.
Fixed tests and added some localization tests too.
Tested on my local development server, with some random languages.
Fixes#23987.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
