When alt + clicking on a link and there is also a mouseup handler that selects some text, the click event doesn't fire. Selecting the text doesn't have to be on the mouseup handler, it can also happen if its in a focusin handler for instance. I believe it is because alt + click in Chrome attempts to download the link target which could be getting confused when some text is selected.

What steps will reproduce the problem?
(1) Navigate to https://jsfiddle.net/SamMiller/c7tgx5Lw/
(2) Open the console.
(3) Click on the red square so that it has focus.
(4) Alt + click on the link.
(5) Notice that the console never reports that a click happens.
(6) Now just click on the link without holding the alt key down.
(7) Notice that the console reports the clicks on each of the elements.

What is the expected result?

The click event should fire even if alt is being held down.

What happens instead?

The click event never fires.
