Media Trash: Primary button(s) should be on the left

[garrett-eclipse]

Following the #design chat it was flagged that the Media Trash primary button(s) shouldn't be on the right;

Quoting @afercia;

Also: why primary buttons are on the right? :)

This came from the design discussion surrounding #44675 and is related to #46757 which denotes there should only be one primary button.

Bulk Media Trash Select showing primary buttons on the right, should be on the left

I'm not sure that we can move the buttons around yet, at least until #46757 is resolved. Mainly because we don't know which button will be the primary

[garrett-eclipse]

Thanks @ianbelanger I agree with you there. That being said with what info we have now I would suggest the following order;
Restore from Trash | Delete Permanently | Cancel
*And in #46757 I suggested the Delete get a new button class to mark it important as it's potentially irreversible.

Flagging for design review as well in hopes both tickets end up in the same scrub discussion.

Moving to Future Release, pending resolution of #46757.

[afercia]

As in this release cycle there's some focus on improvements for the media views, due also to the WPCampus accessibility report, I'd like to propose this ticket for 5.3 consideration together with #46757.

Note: a patch that fixes this issue is uploaded to #46757.

Reopening this so it can be back-ported to the 5.2 branch.

[JeffPaul]

This also needs testing to validate if this ticket is good to land in 5.2.3.
