[Bug] Ads cause the page title to become weird gibberish, e.g. "YouTube Premium apn emp 1mon Expl Stock 30s horiz 1920x1080 ..."

Unsure if this is related to #400 (but to be clear, I don't have Tweaks for YouTube installed).

Note that the page title isn't fixed even after the ad finishes playing - except, strangely, if I move the tab into another window.
