Element android doesn't correctly render closed pre/code blocks.

**Describe the bug**
Element android does not render some events correctly.

**To Reproduce**

Given this event:
```
{
"type": "m.room.message",
"content": {
"msgtype": "m.text",
"body": "```\nredis 38511 14.3 0.0 184916 7760 ? Ssl Jul20 16606:55 /usr/bin/redis-server 10.102.243.76:6479\nredis-e+ 32187 0.1 0.0 721232 24668 ? Ssl Sep21 35:44 | \\_ /redis_exporter\n```\nah, maybe more CPU if it gets busy, but even so",
"format": "org.matrix.custom.html",
"formatted_body": "

redis    38511 14.3  0.0 184916  7760 ?        Ssl  Jul20 16606:55 /usr/bin/redis-server 10.102.243.76:6479\nredis-e+ 32187  0.1  0.0 721232 24668 ?        Ssl  Sep21  35:44  |   \\_ /redis_exporter\n

\n

ah, maybe more CPU if it gets busy, but even so

\n"
}
}
```
View in element web and element android
**Expected behavior**
It should look the same;

However on element android the text after the code block is still in preformatted text mode when it shouldn't be.
