Hello.
I thinked that I had meeted a bug, Now I have 4 tabs in a blazor page and each tab has one richtexteditor at least, if I switch the tab as fast as I can so that I get the NullReferenceException.

BTW, When I type in the RichTextEditor, sometime its status looks like 'PAUSE', I found it happened every 5 seconds I thinked.
Look forward your reply.
Thanks.
