Description:
Emoji will still be rendered even if the surrounding text is recognized as a URL.
Steps to reproduce:
- Open any chat, such as a direct message to yourself or a thread within a channel.
- Enter a url that contains a colon-delimited abbreviation for an emoji, for example
https://example.com/?cmdNode=b8:flag_lv:b9:c2
Expected behavior:
The URL should appear in text form as I entered it and become a clickable link.
Actual behavior:
Sequences within the URL that match the colons-delimited abbreviations for emoji are rendered as such instead of text. The linked URL is still functional and does not contain the emoji, only the display is incorrect. To prevent this, the sequence between the colons must be interrupted by a space or something similar, which will break the link.
