Issue: PathMetric.getTangentForOffset angle values are not smooth on mobile web 
Labels: engine,platform-web,e: web_html,has reproducible steps,P2,found in release: 3.10,found in release: 3.12,team-web,triaged-web

### Is there an existing issue for this?

- [X] I have searched the [existing issues](https://github.com/flutter/flutter/issues)
- [X] I have read the [guide to filing a bug](https://flutter.dev/docs/resources/bug-reports)

### Steps to reproduce

Read values from `PathMetric.getTangentForOffset(n)?.angle` along a curve (in this case created using `quadraticBezierTo`), where `n` is a gradually increasing value from `0` to `PathMetric.length`.

### Expected results

A smoothly changing sequence of rotation values.

### Actual results

On most platforms (mobile, desktop, desktop web), it returns the expected results (a smooth sequence of values):

However, on mobile web, it returns values that change very slowly, then jump ahead suddenly, which creates a very jerky result when using it for animation:

Note that the `position` values returned on mobile web remain smooth, only `angle` is affected.
