I would also "assume", the remote will work with LibreELEC.

You assume too much. I doubt this Wireless remote will work at all with LibreELEC without some modding.

You need to use a Wireless USB dongle remote like the MINIX A2 lite for dual boot Android / LE setups.
Otherwise a BT remote has to be re-paired each time you switch Operating Systems. 

I stand corrected, been awhile since I used my Mecool M8S Pro, it runs LibreELEC and my tvheadend server, so it just sits on my network as my DVR backend.  I just tested it, and my Xiaomi Bluetooth remote does NOT work.  Old age, I guess, I thought my Bluetooth remote worked with it.
