Update env() support in Chrome for Desktop (#3244)
Update env() support in Chrome for Desktop (#3244)

According to this Chromium bug:
https://bugs.chromium.org/p/chromium/issues/detail?id=860604
Initial Chrome 69 release brought env custom properties support, but without defining the safe-area variables. Later fix added default values of 0px on Desktop too:
https://chromium.googlesource.com/chromium/src.git/+/817ca3d4d1ddf5e8571bb79eccf8d73f6efa65c3
If I'm reading this correctly, this fix landed directly in release?
