This does not fix the issue where webkit browsers cannot use it, I looked
at webkit versions in safari and was a bit confused. The wikipedia page
for safari shows v15 having webkit v612+ but I have safari v16 and it's
webkit v605, so trying to detect it based on webkit version is a risky
change.
Note that webgl2 shipped in safari 15, but it didn't work in webgl until
safari 16.
