Element-web: Cannot reject invite from a dead/malfunctioning homeserver

[turt2live]

Description

I invited myself to a room from a test homeserver. That test homeserver has the capability to reach out, but not always be reached. The invite refuses to accept (obviously) and cannot be rejected. I should be able to remove this invite so I'm not stuck with a badge.

Steps to reproduce

• Receive an invite over federation
• Have the sending server die
• Cannot reject invite

Log: not sent

Version information

• Platform: web (in-browser)
• Browser: Chrome 58
• OS: Windows 10
• URL: riot.im/develop

Looks like #3201, which was supposedly fixed by matrix-org/synapse#2145.

I still have this issue with synapse 0.21.1-1 & riot 0.11.2
Accept, reject, decline and decline all x invites won't remove it.
I got this invite from someone who discontinued his HS before I could accept it.
My HS logs this when I try to reject it:

was this supposed to be fixed by matrix-org/synapse#2145 ? it still is an issue for me

[nim65s]

Still got this issue, clearing riot's cache fixed it.

bumping prio as per https://github.com/vector-im/riot-web/issues/8943 (copied major from there also)

[RebelCoderRU]

Still got this issue, clearing riot's cache fixed it.

This does not work as this is not a local problem. All of my devices, logged in to my matrix account show that broken invite.

In which case the place to report your bug would be https://github.com/matrix-org/synapse/ as its Local Rejections are not working as they should be.
