Blank webview on Android when displaying large content

[andreialecu]

Bug description:

I'm using https://github.com/formidable-webview/webshell to wrap react-native-webview in order to embed the webview inside a ScrollView and have an auto-height for it, in order for other native components to be laid out at the bottom of it.

It appears that when the content in the view passes a certain threshold, it starts rendering blank. It still takes up all the space it needs to, so there are scroll views present, just that the entire space is empty.

Upon checking Flipper, I noticed this error logged in the Android system logs:

chromium: [ERROR:tile_manager.cc(811)] WARNING: tile memory limits exceeded, some content may not draw

To Reproduce:

Pass some large content with multiple large embedded base64 images as the html source (pass a string of the entire html). I haven't verified if this also occurs with URL sources.

I can reproduce it on both the emulator and a real device.

Expected behavior:

Content should render.

Screenshots/Videos:

Reusing screenshot from iou90/react-native-autoheight-webview#241

Environment:

• OS: Android
• OS version: 12
• react-native version: 0.68.1
• react-native-webview version: 11.22.7
• Android System Webview 91.0.4472.114

Likely relevant: the html I'm passing in includes several base64 encoded images and is 15,450,504 bytes large.

However, the html rendered in the report at iou90/react-native-autoheight-webview#241 is much smaller.

I have noticed this occurring before with other data myself. It could be related to auto-height webviews.
