using keyboard shortcuts to copy messages with mentions will strip out the mentions

Observed behaviour

the mention is discarded. only the plaintext components get copied to the clipboard. my clipboard does not contain the <@...> syntax, or any other substitute.

Reproduction steps

be using a keyboard with clipboard controls, such as Google Gboard
enter any message in the chat input which contains syntax that renders inline (i.e. mentions)
copy the message using the clipboard functions in the keyboard. (do not use the tooltip rendered by the app; that one isn't buggy)
paste what you just copied back in to Fluxer
