Open Bug 1321810 Opened 4 years ago Updated 3 years ago
(E10s) Pressing Left/Right/Up/Down arrows has different functionality when E10s is enabled/disabled
STR: 1. Navigate to https://people.mozilla.org/~mnoorenberghe/w3c_notifications.htm 2. Click the Direction datalist 3. Navigate through the list by pressing the left/right/up/down arrows. Actual: E10s=True: Pressing Left/Right arrows does nothing. E10s=False: Pressing Left/Right arrows navigates Up/down through the list. Affected OSes Windows and Ubuntu
This should only happen on Windows.
OS: Unspecified → Windows
This also happens on Ubuntu 16.04. I just verified
OS: Windows → All
But it shouldn't happen on Ubuntu. GTK dropdowns don't do this, so we shouldn't either.
OS: All → Windows
I don't understand #c3: Are you saying that it navigating through using arrows shouldn't work on Ubuntu regardless of e10s? Either way, the behavior on Ubuntu sounds inconsistent between e10s and non-e10s.
It shouldn't work on Ubuntu in either case, but with bug 1300784 we aren't concerned with non-e10s in Firefox.
OK. So if I understand this correctly, this bug has two parts: 1) the behavior is wrong on Windows: pressing Left/Right arrows navigates Up/down through the list should be consistently true on both e10s and non-e10s; 2) the behavior is wrong on Ubuntu: pressing Left/Right arrows navigates Up/down through the list should be consistently false on both e10s and non-e10s.
That's correct. This is a very low priority issue though.
Neil: do you have an opinion on what should happen when we use a vertical writing mode for the <select> popup (see bug 1170129)? My instinct is that the arrow keys should respect whatever the visuals look like, but maybe that's not what users expect... The old <select> popup always interprets "right" to mean "next item" (and similar for "left"), but that doesn't seem right for vertical-rl writing modes.
Whoops, forgot to ni? you; see comment 8.
As far as I know, there is no 'vertical mode' dropdown/combobox type widget anywhere in any existing UI system so I don't think there's any precedence to follow, nor would users have any expectation as to what would happen. I would think that users would expect select elements to always be rendered horizontally. If there does exist such a UI control somewhere, then we should follow what that does.
Sound like adding a navigation for vertical writing mode would be an improvement but fairly low priority. I think this can drop off the platform triage list.
[Triage] Coming back this issue several months later, it's still thought a very low priority issue as comment 7 suggested. Setting P5. Feel free to change as you see fit.
