Summary: Crash with the new syntax highlighting
Classification: Applications
Product: NeoChat
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal

SUMMARY
I am using the kdesrc-build version (so master build) of neochat and it seems
if message contains this snippet in a room, it crashes Neochat when trying to
open that room.
```html
<main>
<data value="2"></data> <!-- push 2 onto the stack -->
<data value="3"></data> <!-- push 3 onto the stack -->
<dd></dd> <!-- add the top two values on the stack -->
<output></output> <!-- print the sum now on the top of the stack
-->
</main>
```
The raw json part of the message is like following:
{
"content": {
"body": "```html\n<main>\n <data value=\"2\"></data> <!-- push 2 onto
the stack -->\n <data value=\"3\"></data> <!-- push 3 onto the stack -->\n
<dd></dd> <!-- add the top two values on the stack -->\n
<output></output> <!-- print the sum now on the top of the stack
-->\n</main>\n```",
"format": "org.matrix.custom.html",
"formatted_body": "<pre data-md=\"```\"><code
class=\"language-html\"><main>\n <data
value="2"></data> <!-- push 2 onto the stack -->\n
<data value="3"></data> <!-- push 3 onto the
stack -->\n <dd></dd> <!-- add the top two
values on the stack -->\n <output></output> <!--
print the sum now on the top of the stack
-->\n</main>\n</code></pre>",
"msgtype": "m.text"
},
STEPS TO REPRODUCE
1. Open a room
2. Send the html snippet from above in that room (from any other client)
3. Close and open the room with the message that has the html snippet
OBSERVED RESULT
Crash
EXPECTED RESULT
Pretty colors
