Tabbing through a Trac ticket before submitting a comment results in it being closed with no resolution

I thought there was a ticket for this already, but I couldn't find it.

Tabbing through the form inputs on a Trac ticket results in the focus passing through the action_dupe text input. When this input gets focus, the "mark as duplicate of #" radio button gets automatically checked. When the form is submitted, the ticket gets closed but without a resolution because no duplicate ticket number is entered.

This means it's impossible to use the keyboard only to submit a comment on Trac without closing it.

Note that @arush just experienced this on ​#WP35479.

Actually, it's not impossible to leave a comment without closing it, but it's difficult.

Trac has ​some JS code to handle this, but it's overridden by some of our own code​.

meta-1521.patch​ fixes this by hiding action text inputs from keyboard, unless the corresponding action is focused. It also allows for select inputs to be clicked directly as well (in addition to text inputs).

In 2310:

Trac: Don't make action text inputs and select fields focusable until the corresponding action is focused.

Also allow action select fields to be clicked directly.

Props SergeyBiryukov.
Fixes #1521.
