AliExpress runs silent WebAudio fingerprinting that breaks Bluetooth multipoint

AliExpress runs hidden WebAudio fingerprinting scripts that interfere with Bluetooth multipoint functionality on connected devices. When users load the AliExpress homepage, two obfuscated audio contexts are created silently without any visible media, which disrupts the audio priority system between paired devices like PCs and phones. The fingerprinting scripts, part of Alibaba's anti-abuse tooling, can be disabled by closing the AliExpress tab.
