Resolved
This issue was present in 1.19 Pre-release 1, but no longer occurs in versions above or equal to 1.19 Pre-release 2. With that being said, this issue has been fixed in 1.19 Pre-release 2. To reinforce my claims, I've attached two screenshots. Pay close attention to all instances of the subtitles overlay in both attachments and notice the change in behavior between versions.
