Yup, still The Boys ;)

Input:

00:33:41,770 --> 00:33:45,023
There's <i>Homelander: Origins.
Homelander: Rise of a Hero.</i>

Output:

00:33:41,770 --> 00:33:45,023
There's <i>- Origins.
- Rise of a Hero.</i>

Expected output:

00:33:41,770 --> 00:33:45,023
There's <i>Homelander: Origins.
Homelander: Rise of a Hero.</i>

I don't have an easy fix for this one. Maybe detecting title case? Would that work without introducing false negatives? o.0

Also not sure how best to handle this, i suspect it would likely be too destructive a filter. The relevant code to modify would be here.
