[severity:Other]
Some of the users of my software have reported the following problem with emojis and the Microsoft Rich Text Control - and I can reproduce the problem:

The problem is that inserting emojis into rich text controls that contain bullet points, frequently causes the bullets to
disappear. It doesn't always happen with all emojis. It may be that some emojis are worse than others. Also, it appears to happen more easily with Windows 11 than with Windows 10. Here is one (of many) ways to reproduce:

Using Windows 11, type the following text on 4 lines, into a dialog containing a Microsoft Rich Text Control (you will also need to have a way of getting the control to add bullets):

OK
One
Two
Three

Position the cursor right at the start, before the word 'OK'. Press the Windows (flag) key + '.' (the full stop) on your keyboard. The emoji popup window opens. Click or double-click a few times on the 'Heart' emoji, to insert heart emojis. These go in OK (black-and-white version). Now select lines 2 to 4 and use your method, whatever it is, of forcing these lines to be bullet-points. When you do this, the lines become indented, but the bullets do not display.

Actually, this works even if the bullets were already there. They would just disappear. Deleting the emoji does not immediately fix the problem.

The above method doesn't work for me in Windows 10 (i.e. in Windows 10, the bullet points display OK if I do the above). This only works consistently in Windows 11. I can get the problem to occur in Windows 10, but less consistently.
