1208928 - Ctrl+Click doesn't press <input type="number">'s spin-up/down buttons even though they look depressed

Status: NEW

(Core :: Layout: Form Controls, defect)

Description

[arni2033]

STR:   (Win7_64, Nightly 44, 32bit, ID 20150926030216, new profile, safe mode)
1. Open the following "data:" url or click URL in the form above
>   data:text/html,<input type="number"/>
2. Ctrl+Click spin-up button

Result:       Button looks depressed, but nothing happens
Expectations: A) change input's value, or
              B) don't look depressed, but in this case there's no visible difference between
                 pressed and not-pressed button compared to simple click w/o Ctrl.

Note that currently those buttons don't look depressed when you simply click them.

This seems to be Windows only.

It's also pretty low priority, but basically the content code ignores clicks with most modifier keys:

Whereas the Windows native theming code only examines Element::State() (via nsNativeTheme::GetContentState):

Do you think I should file separate bug since those buttons DO look depressed
on (Ctrl/Alt/Shift)+Click, but don't look depressed on simple Click? That makes a very bad impression

No, this bug can cover all that.
