Describe the bug

Dearrow appears to be adding some inline markup to the video titles, indicating whether some capitals should be kept even when applying things like titlecase modifiers to the custom title. This can be seen on the video Uuh_T648J_8 for example:

> curl -sS https://sponsor.ajay.app/api/branding/74db | jq -r '.["Uuh_T648J_8"].titles[].title'
Building >Tally >Ho's standing rig | >Rebuilding >Tally >Ho >E176
Building >Tally >Ho's rig | >Rebuilding >Tally >Ho >E176

As far as I can tell, the exact format of this markup isn't documented anywhere. I inspected the browser extension source to confirm it is parsing it, but the logic is quite convoluted so I haven't fully worked out what it's doing with it.

(sponsorblock mention for searchability)

Expected Behavior

Dearrowed video titles are rendered without the markup.
