[BUG][mgt-chat] HTML tags visible after editing chat within MGT mgt-chat component

[Laurence-V]

Describe the bug
When editing in the mgt-chat component of MGT, the client renders HTML tags, these then persist on web/fat client if changes are made and saved. The HTML tags are not rendered in the mgt-chat component on saving.

To Reproduce
Steps to reproduce the behavior in MGT:

1. Go to a system running chats using MGT
2. Click on a message you have sent to get the context menu and select Edit
3. The message will become editable
4. Error: The message now shows the HTML tags, while in Edit Mode

To see in Web/Fat client

1. Make a change while in the MGT chat component, while in Edit Mode
2. Accept change
3. Go message to Web/Fat client
4. Error: The message now shows the HTML tags

Expected behavior
HTML tags should not be visible in the clients

@Laurence-V this is a valid bug. I'm moving it to our backlog and it'll be fixed as soon as possible

Thanks @musale,
I've also noticed that in the MGT component, Less Than and Greater Than get converted into HTML
And that HTML Tags get rendered correctly i.e. with <> but they also get auto completed in the MGT component
Whereas in the (New) Teams client, they are rendered as entered.

@Laurence-V the processing of the Teams messages in mgt-chat is done by parsing the html text so I would suggest that these edge cases are given an independent look. Could you make this another issue so that we can track other scenarios too?
