AudioStreamPlayer doesn't loop with parameters/looping set to true in web export

[elpozewaunig]

Tested versions

• Reproducible in 4.3.stable, 4.4.dev7

System information

Godot v4.4.dev7 - macOS Sequoia (15.1.1) - Multi-window, 1 monitor - OpenGL 3 (Compatibility) - Apple M1 Pro - Apple M1 Pro (8 threads)

Issue description

Looping an audio stream in an AudioStreamPlayer only works when the file is imported with the loop property set to true in web exports. Using the parameters/looping property of the AudioStreamPlayer node does not loop the audio, whereas this works as expected on desktop exports and in the editor. This occurs both with threads enabled and disabled and has been tested in Firefox 133.0.3 and Chrome 131.0.6778.205.

Steps to reproduce

1. Create new scene
2. Add AudioStreamPlayer node, add an AudioStream (with the loop import property set to false), set autoplay to true, set parameters/looping to true
3. Run project in web browser
4. Observe that the stream does not loop

Alternatively:

1. Open minimal reproduction project
2. Run project in web browser

Only happens when the project setting audio/general/default_playback_type.web is set to Sample (the default), cc @adamscott
