getRtlScrollAxisType detects incorrect RtlScrollAxisType for safari

[kimjuan]

What is the expected behavior?

In safari,

getRtlScrollAxisType() === RtlScrollAxisType.NEGATED

What is the current behavior?

getRtlScrollAxisType() returns RtlScrollAxisType.INVERTED

What are the steps to reproduce?

Providing a StackBlitz reproduction is the best way to share your issue.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

• Angular/Angular Material 7.0.4
• macOS 10.13.6
• Safari version 12.0.2 (13606.3.4.1.4)

Is there anything else we should know?

Problem unlikely to do with safari and os. Other libraries detected it correctly using feature detection technique

Hello, on my end the RTL scroll axis type is set to NEGATED in Safari (as expected). Can you please provide a reproduction if this is still an issue? Thank you!

This is the demo I used: https://stackblitz.com/edit/angular-yehn5j?file=src/app/cdk-platform-overview-example.ts

Happy to re-open if you can point us to a demo that shows the issue.
