The way to disable bracketed paste mode is presumably to place this in .inputrc:
set enable-bracketed-paste off

But DON'T do this! Bracketed paste mode is an important safety measure against malicious or accidental pastes that contain embedded newlines. See https://thejh.net/misc/website-terminal-copy-paste .

What you should be looking for is to preserve bracketed paste mode, yet revert to no highlighting, or customize the highlighting colors. I don't know how to do that because I haven't studied this new bash "feature" yet. If you look it up and find it, please post the answer here :)
