Before testing, please apply whole native stack.
1. Create a community with three users.
2. Create a private chat for two chosen users.
3. Mention private chat in community chat (e. g. @[[256|8282:default text]]).
For users assigned to previously created private chat, the mention should be bold and render current thread name:
{F697982}
For users who are not in private chat, the mention should be rendered with plain text message style:
{F697980}
