Left-handed mouse settings not applying in-game

I am left-handed, so on my PC, I have my mouse set to left-handed settings. Before 1.21.120, this worked just fine, with the right mouse button functioning as it would normally on a left-handed mouse. However, as of 1.21.120, this no longer applies, and now my left-handed mouse functions as a right-handed mouse in Minecraft Bedrock Edition 1.21.120.
