How to change subtitles position on my iPhone 15 Pro?

I’ve noticed a frustrating issue with subtitle display on my iPhone devices. Single-line subtitles often touch the bottom edge of the screen, while double-line subtitles are slightly raised above the bottom. This inconsistency makes the viewing experience quite unpleasant.

Here’s a breakdown of my setup and troubleshooting so far:

• Devices: iPhone 15 Pro Max (iOS 18.2) and iPhone 11 (same issue on both devices).
• Settings: My subtitle settings are default. I have toggled on/off video override to see if that would fix the issue but it doesn't.
• Browser: Happens in both Safari and Chrome.
• Extensions: The only extension I use is AdGuard. I’ve already tried disabling it, but the problem persists.
• Example: I’ve attached images showing the bug for better clarity.

Is this a known issue? Are there any fixes or workarounds I can apply to resolve this problem?

Thank you for your help!
