[crazyskeggy]

does this occur in all distros? which ones have you tested?

Comment 2

[Paul Adenot (:padenot)]

We have tested Ubuntu so far (last release), I'm going to check other distros when I get a chance.

Comment 3

[Olli Pettay [:smaug][[e-mail]]]

On Gecko NS_VK_SPACE has traditionally fired click after keyup.
NS_VK_RETURN causes click after keypress.

IIRC the behavior is from old Netscape times.

I guess this old behavior can be just taken out then?

Comment 6

[Yves Van Goethem]

After discussing this with Olli on IRC we came to the conclusion that this is an expected behavior and that the focus logic is platform dependent.
Webapps/sites can prevent the default behavior if they want to achieve a consistent experience across platforms.

I guess we can close this.
Cheers!

Still investigating if we could change the behavior.

Comment 8

[Yves Van Goethem]

This is now over a year old, was any decision taken?

Comment 9

[Olli Pettay [:smaug][[e-mail]]]

Any chance to have a testcase which shows where the key event actually is dispatched, in other browsers. Gecko dispatches it to the button if the focus is there.
