This crash is not Android-specific. There have been about 120 Servo_ComputeColor crashes over the last six months, split between Fennec, Fenix, and desktop Firefox.

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
