I'm not able to observe this issue on my Android device, with a build from latest master.

Could you please provide more information about the issue such as:

1. Whether this is on an emulator or a real device?
2. Version of Android running on the device/emulator.
3. Architecture of the device/emulator (arm or intel, 32 bit or 64 bit).
4. Steps to reproduce the issue: Is this intermittent? or consistently reproducible? Did you have to load a different page than the default servo.org page?

I'm testing on a Samsung A52s with the armv7 build, happens always the servo page is not rendered correctly https://ibb.co/gdhsfBM
