Messages with markdown are displayed differently between Android and web apps

[WernerHoltfreter]

Steps to reproduce

When I type "15. April" in the webapp on Firefox and send:

• my own screen still shows "15. April".
• the recipient on Android-App 1.3.9, Matrix-SDK: 1.3.9, OLM: 3.2.4. sees "1. April"
• the recepient on Chrome 96.0.4664 sees "15. April".

When I type "15. April" in the webapp on Chrome

• same result, only the Android-App shows "1. April" (independent of the Markdown 'on' or 'of' on Android)

When I type "15. April" on Android-App with activated Markdown

• only the Android-App shows "1. April"
• Chrome or Firefox are showing "15. April"

Outcome

OK, I learned that is Markdown. But all screens should show the same.

This is a bug with android not respecting the start attribute.

<ol start=\"15\">\n<li>April</li>\n</ol>\n

https://spec.matrix.org/v1.1/client-server-api/#mroommessage-msgtypes lists start as valid for ol tags
