Users cannot send messages in encrypted rooms when m.room.message is inaccessible via power levels

[timedoutuk]

Issue Description

When encryption is enabled, and m.room.message's power level is above users' own (e.g. set to 100), cinny prevents standard users sending any messages at all:

Expected Behavior

Cinny should allow posting (encrypted) messages even if m.room.message (unencrypted message) is disallowed

Actual Behavior

Cinny prevents messages being composed in the first place

Reproduction Steps

1. Create a room
2. Enable encryption
3. Set m.room.encrypted to 0 (so all users can send)
4. Set m.room.message to anything but 0 (so regular users can't send unencrypted messages)

Environement

- OS: Arch Linux
- Browser: Firefox
- Cinny Web version: v4.12.3 (app.cinny.in)

I acknowledge that:

• I have searched the Cinny repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.

Afaik, m.room.encryption in m.room.power_levels means who can enable encryption. I couldn't find anything that says it should control the message sending permission. Do we have this documented somewhere?

[timedoutuk]

Oh yes sorry, that's a typo. I meant m.room.encrypted, will edit
