Feature/Bug: Preserve custom subtitle location on chat updates

[JuggernautJf]

Description

There is an issue where the custom position of the subtitles is not preserved. When I drag the subtitles to a new location on the screen, they stay there temporarily. However, as soon as a new chat message arrives, the subtitle position immediately resets back to its initial/default coordinates.

Steps to Reproduce

1. Open a stream/video with subtitles and chat enabled.
2. Drag the subtitles overlay to a new position on the screen.
3. Wait for a new message to appear in the chat.
4. Observe that the subtitles snap back to their original position.

Expected Behavior

The custom location where the user dragged the subtitles should be preserved/locked, regardless of new incoming chat messages.
