Sending pills as Markdown links in m.content.body is disruptive to bridged IRC channels

[whitequark]

Steps to reproduce

Take a look at this log where an Element nightly for iOS user is causing a lot of noise in the channel: https://libera.irclog.whitequark.org/litex/2023-07-27

Outcome

Specifically their client is sending Markdown in m.content.body every time they highlight anyone. For example:

{
  "content": {
    "body": "[whitequark](<https://matrix.to/#/@libera_whitequark:catircservices.org>) ah yes indeed, thank goodness and silly of me to think you would have forgotten to do that. Might want to point irclogs.whitequark.org to redirect to libera. instead of freenode.?",
    "format": "org.matrix.custom.html",
    "formatted_body": "<a data-mention-type=\"user\" contenteditable=\"false\" href=\"https://matrix.to/#/@libera_whitequark:catircservices.org\">whitequark</a> ah yes indeed, thank goodness and silly of me to think you would have forgotten to do that. Might want to point irclogs.whitequark.org to redirect to libera. instead of freenode.?",
    "msgtype": "m.text"
  },
  "origin_server_ts": 1690465299451,
  "sender": "@jevinskie:matrix.org",
  "type": "m.room.message",
  "unsigned": {
    "age": 758
  },
  "event_id": "$DyJsm6CV8ro0dkNQSSI_p3BOnAP3iEnWAwF3M0KJaeg",
  "room_id": "!LhJjrGmNCUyJajtYYf:catircservices.org"
}

The noise is then further amplified by a bot that posts the page title when it sees a link, but it's plenty noisy without the bot.

I would like Element X to stop sending Markdown for pills in the body or I would have to advise anyone using it in channels bridged to IRC to switch clients.

The user reports they are not using Element X, so I'm closing this report until it's more clear what's going on here.

The correct report should be element-hq/element-ios#7629.
