The Extension contract correctly reduces votes from the from address of a transfer and adds it to the to address of the transfer (in case both of them voted on it before), but it does not rerun the voting logic in voteOnExtension that actually grants the extension.
This leads to issues where an extension should be granted but is not:
Extensions that should be granted after a token transfer are not granted.
Rerun the threshold logic in removeVotes as it has the potential to increase the total support if to voted for the extension but from did not.
