When I try to click on a firewall rule to open it, often it tries to drag the rule and I have to try 5+ times to open the rule. I have been having this issue for quite some time on Chrome stable

If you move your mouse during click (even one pixel is enough), it will obviously detect it as drag. That is not really surprise and as webdeveloper, I can say that it is common distinction between click/drag on most of sites. This issue obviously is not caused by developers but by user - only one truly universal solution exists - do not move your mouse during click.
This is a sensitivity issue. On Firefox there is no issue but on Chrome the chances of click treated as drag is much higher 2 applications I have seen (one is Mikrotik Firefox UI, the other is eve-ng/unetlab)
This is actually a focus issue I think, very annoying
