Code block bug? or missing documentation of reason message not sent in help article.

The article I am referring to: https://support.discord.com/hc/en-us/articles/360060145013

That article is the help message that appears in discord when you send a message that could not be delivered. I am not sure if I have found a bug or something not very well documented that has been bugging me.

(this bug may happen with other characters simplified by discord but tabs are the most common I believe and the one most programmers encounter.)

When trying to send a regular message with a bunch of tabs it immediately simplifies them down to spaces, but when you do for code blocks it leaves them until you send the message. This can cause a "bug" where (I believe) it tries to send the message but in turning all the tabs to spaces it then realizes it is too long and won't send. But instead of giving an error saying it is too long or saying you have too many tabs, it says "Your message could not be delivered." and gives the article given above for help.

In that article I found no mention of this happening, and it took me a while to figure out what this was and why it was happening. It has happened to lots of my friends too, and they are less good with computers so they didn't realize what was happening at all or how to fix it and it took a while to solve.

My suggestion is to simply add to the help article and say "this can also be caused by message compression, and means it is too long." or something along those lines. Anything to hint at that being the error and not them blocking you or not being your friend.
