Dragging tabs won't reconnect with browser

When I drag a tab it disconnects from the current window creating a new window, but will not reconnect to the window it was dragged from.

Brave Version: 1.34.80 Chromium: 97.0.4692.71 (Official Build) (64-bit)

Running Debian 11 Bullseye.

Same problem for me.
It’s really annoying because I enjoy brave (on Arco Linux KDE)

I was tempted to reset defaults, but it removes extensions and cache, and I’m concerned what that would do to rewards.

I my try that next reward payment, so any potential loss is minimal.

not sure if this is worth a look
