Hello!
Select the widget on the board -> open the user application panel -> close the user panel -> remove the selection from the widget. Now if you open the panel again and close it again, the widget will stand out by itself. Moreover, even if the widget is removed, then after closing the panel, dots will fall into the selection (which should not already be on the board).
This bug is definitely not because of my code, because I created an absolutely empty application (below I will give the code that I wrote). This bug appears in my other apps as well.
miro.board.ui.on("icon:click", async () => {
await miro.board.ui.openPanel({url: 'proba.html'});
});
For clarity, I present a video from a file sharing site (it will be available for 6 days).
