Description
### Steps to reproduce
1. Receive a DM of a 25x25 HTML table full of emojis (like the one in the attached file)
2. Open app
[table.txt](https://github.com/vector-im/element-android/files/9460341/table.txt)
### Outcome
The app becomes totally unresponsive. I had to open the DM on PC and delete the message just to be able to use the app on mobile again. Spamming emojis does not do this, and sending large HTML tables full of text does not do this. Only sending a large HTML table full of emojis.
