802.11 and 802.15.1 interfere on Arch but not Windows

I'm dual-booting the 4.19.93-1-lts arch kernel on a 2019 Samsung Notebook 9 Pro (np930mbe-k04us).
With Bluetooth headphones I get perfect sound on Windows but I hear glitches on Arch.
My solution, which I discovered on the Bluetooth headset wiki page, was to switch to 5Ghz wifi.
Now the audio is perfect, just like on Windows.

The aforementioned wiki page makes this comment about glitching:

This is very likely to occur when the Bluetooth and the WiFi share the same chip as they share the same physical antenna and possibly band range (2.4GHz). Although this works seamlessly on Windows, this is not the case on Linux.

I'm curious - what causes this difference between Windows and Linux?
