Cannot load a different page on an already loaded tab on a Xiaomi device with Android 5

Steps to reproduce

1. Load wikipedia.org, or any other page.
2. Tap the toolbar, and type a different address, like cnn.com.

Expected behavior

The page from step 2 loads replacing the page from step 1.

Actual behavior

The page from step 1 is still displayed, on the top of the screen, leaving the bottom of the screen blank.

A similar issue is reproducible on RC 98.3.0 with Huawei MediaPad M2 (Android 5.1.1) when attempting to crash the app using about:crashparent. The bottom half of the page remains empty and the app remains unresponsive, without crashing.

@delia-pop Can you please also add a logcat for accessing about:crashparent and then getting that ANR message?

@Mugurell I reproduced the issue on Focus Beta 99.0.0-beta.5 with Huawei MediaPad M2 (Android 5.1.1). Logcat_ANR_TabA5.txt

I was not able to reproduce this issue on the latest Focus Nightly 102.0a1 from 5/26 with Xiaomi mi4i (Android 5.0.2).

[delia-pop]

I can still reproduce this issue as described above with Huawei MediaPad M2 (Android 5.1.1) on Focus Beta 104.0b2.
