Stop the automatic opening of new "windows"

Having the same issue on Android 13. If I use Android’s share (because it’s not the default browser) to send a link to Brave, it seems to open a new window instead of tab. I discovered this because there is apparently a limit of 5 open windows.

If I go back instead of going home, it sometimes closes it, but not reliably. It also seems to have old tabs open in these new windows, ones I closed days or weeks ago, that I discover when hitting the tabs button and viewing the open tabs.
