Yeah, mobile issue.

I'm expecting a scroll behaviour, then a second later I see a preview window popping up giving me menu options for e.g. open in new tab, but that preview acts like clicking the link…

It is an issue on desktop, though only for submissions. The flag link is next to the hide link (which I use constantly), and because the username and time are to the left of these, the flag and hide links are in a different position for each submission leading to regular mis-clicks.

It's next to the 'hide' link, which I use all the time. It's easy to hit 'flag' instead of 'hide'.

Pretty much yeah, it's easy to mis-tap.
