Windows hangs on MediaControls::set_metadata()

[hinto-janai]

Hello, first of all - thanks for this library.

I have some code interacting with souvlaki, based off one of the examples to create a dummy window.

I'm encountering some issues on Windows 10 Pro 10.0.19045 Build 19045.

This line inside of MediaControls::set_metadata() will hang forever:

souvlaki/src/platform/windows/mod.rs

Line 188 in 384539f

let results = loader.get()?;

Calling pump_event_queue() has not been necessary in my case on other machines for quite a while, but I added it back just in-case, however MediaControls::set_metadata() still hangs.

The file:// URL passed is a normal PATH to an image file.

This code does work on some other Windows 10/11 I have though, so I'm not sure what's going on.

To be honest, I'm not familiar with the code of the dummy window since it was merged in a PR (#34). It seems pretty strange that it would only fail in that build though.
