Underline on links inconsistent depending on whether or not the message is formatted

[turt2live]

Description

The first link is just a plain m.text event:

{
    "body": "https://matrix.org",
    "msgtype": "m.text"
}

The second link is sent with a custom format though:

{
    "body": "https://matrix.org",
    "msgtype": "m.text",
    "format": "org.matrix.custom.html",
    "formatted_body": "https://matrix.org"
}
