this appears to be a bug in esbuild browser version detection

Please see: #21699

[zackschuster]

i had supports es6-module in .browserslistrc, same as the linked issue. adding not safari tp indeed fixes the build. still seems kind of weird overall, not just to have to do that but that it only affects css compilation (??).

[alan-agius4]

Browserlists also effects JS downleveling when needed.

In future it is not excluded that it may effect other features, so configuring explicitly the browsers that your application needs to support or leaving the default config is definitely recommended.

supports es6-module is also too broad and the majority of resulting browsers are not supported

Note: the supported browsers should be the full or subset of browsers that the Angular framework supports.

[zackschuster]

angular's official window of support is extremely short, which is specifically why i went for that config. the compiler should not error out-of-hand over such things, especially when the subset of features i use strictly conforms to a 2017-era compatibility matrix. if i want to go beyond what angular supports, then angular should not get in my way.
