Cannot seem to copy/paste text between brave and alacritty using right mouse button

Hello, I seem to have lost the ability to copy text into a global clipboard using my right mouse button anymore.

So, I select text from Alacritty and select copy when holding my right mouse button. then, I go into the search bar in Brave, click and then select paste when holding my right mouse button.

Expected behavior: Text that I think I copied form Alacritty should be pasted into the search bar.

Observed behavior: Text from some other copy event is pasted in.

Totally confused. This used to work for me. Any and all helpful suggestions appreciated!
