Expected Behavior

The arrow keys in a browser interact window should only register once when pressed, unless held.

Current Behavior

The arrow keys register twice when pressed once. For instance, when the left arrow key is pressed once in a text field, the insertion point moves two spaces to the left.

Steps to Reproduce

1. Add Browser Source
2. Link source to any site with a text field (Google, DuckDuckGo, etc)
3. "Interact" with source
4. Type in text field
5. Move insertion point with arrow keys to demonstrate problem
   ...

Anything else we should know?

I've noticed that OBS only behaves this way on MacOS (both x86 and Apple Silicon through Rosetta). Linux Mint did not have the same issue and testing over the phone with a Windows user did not produce the same problem.

For me, this causes problems for HTML slideshow presentations. The slide moves two forward or back instead of one!

Start by reproducing the issue through OBS Studio's Browser Source and Interact window on macOS, using a text field and a slideshow if available. Trace the macOS keyboard-event path used by the browser interaction entry point and compare it with Linux or Windows behavior. Done means one arrow press moves the caret or slide once, while holding the key continues to repeat normally.
