Antivirus blocks element.io

### Steps to reproduce

I am not sure if this is a security issue or a problem with Sophos.

Sophos Threat Management blocks https://element.io due to `MAL/HTMLGen-A`

* Open https://app.element.io
* Connection is reset with message "Access has been blocked due to MAL/HTMLGen-A" (freely translated from German)
MALGen-A means this: https://www.sophos.com/de-de/threat-center/threat-analyses/viruses-and-spyware/Mal~HTMLGen-A/detailed-analysis.aspx
