CAUSE: TinyMCE v5.10.9 and v6.7.3 explicitly changed how the "zero width no-break space" character(U+FEFF) is handled. Unfortunately, the mention plugin uses U+FEFF as a delimiter for the user-entered search text.
SOLUTION: Change the U+FEFF character to U+200B ("zero width space") in the 2 places it is used.
Fixes #93 .
