it usually happens on a cold start. as in, it is running in background because you used it for a while. and then after a while, you load it and it opens a blank page lol.
url thing goes something like this. i see a news article on x/discover. i open it. i decide to post it on forum. so i copy the url from the address bar and type the forum link where i want to post it. press enter. chrome tries to open the forum link for a second but stays on the current page. lol. not happening right now so maybe it was temporary.
