I had the same problem too, drove me nearly nuts. I spent 3 days on this. Check out the following:

Body height. Not just the css height, but also physically check the height, I use mozilla firebug to select the body attribute, this highlightes it. If it's above the element, or selection area, it will give the bug. Also css for the specific area to select, and body

-moz-user-select: none;
-webkit-user-select: none;
-ms-user-select: none;
Make sure your user selection is !!NOT!! none.

Hope this helps you out.. I did read some very frustrating posts regarding this issue, and it was not an easy find either, I found it quite by chance.

if you are using Visual studio code for debugging, just make the All Exception unchecked in the breakpoints section .

Answer 3

Just to add what I found on Chrome/OSX in a particular scenario. I found this using .is(':visible')

It shows up in the log when it is called from a function executed in a setTimeout() but works just fine.

Uncaught SyntaxError: Unexpected identifier
Failed to execute 'matches' on 'Element': ':visible' is not a valid selector.

I'm not sure the reason, but I pulled the use of setTimeout and moved on.

I had the same issue and solved it by restarting the browser. It seems to have disappeared.

I had this problem on Firefox 57.

The "breaking on exceptions" documentation tells us that "pause button (II)" has three states. The light purple state is the one that we want: It shows uncaught exceptions, but ignores caught ones.

Answer 6

The * selector selects all elements, therefore combining it with other selectors, e.g. *,div, is unnecessary.
