Anyone Ever Experience Something Like This As Well?

So I was scrolling my YouTube feed when I came across a post about President Trump. Never one to let opportunity slip I may have added a comment about how “proud and excited I was to have a president who was finally brave enough to acknowledge the existence of UAP’s and Non human biological entities but also release the files on the subject”. Etc.. You know, just the normal ego bolstering affirmations needed to help certain individuals follow through on the difficult things they said they’d do..

Anyways I never had this happen before and it very well could have just been a glitch but when posted it, my screen froze for just a split second with what looked like circled marks around certain areas of my comment. What’s weirder is my comment disappeared. My comment does not show up on that post now. Maybe I’m just overreacting to a normal glitch but either way I’m curious if anyone’s ever had or heard of something like this before?
