ARIA 1.0 Combobox Examples: Escape key does not behave correctly when focus is in the textbox

[mcking65]

The combobox with both list and inline autocomplete does not process the escape key correctly when focus is in the textbox.

When focus is in the textbox, if the popup is displayed, Escape should collapse it. Optionally, it can clear the value. It does neither.

OK, this is confusing. I have not yet merged Jon's fix in pull #734, but I cannot repro the bug on the latest version in master. However, I can repro in the published version on w3.org. Yet, In the history of the js for this example, there have not been any changes since before we published.

Use the following procedure and observe the difference between the published version on w3.org and the current version in master. Note, if using JAWS, press insert+z to disable VC.

1. Type "c" in the combobox.
2. Press Delete to delete the "alifornia" that appeared inline.
3. Press escape.

Behavior on w3.org: Nothing happens when escape is pressed.

Behavior on master: When escape is pressed, the listbox collapses and the "c" in the textbox is cleared.

So, something has fixed master without merging the fix. I don't want to merge #734 if it is not necessary.

There are three files in the JS dir for the combobox 1.0 examples. Their latest commits in master are:

1. combobox-1.0-list.js: Commit 3048bac on Nov 27, 2017.
2. listbox.js: commit 3048bac on Nov 27, 2017.
3. listboxOption.js: Commit 3048bac on Nov 27, 2017.

And, just to be sure ... I checked out the release used to publish the note to make sure that 3048bac is in the history ... and it is:

$ git checkout apg-1.1r1

HEAD is now at 83217c0 really? I have to say WG-NOTE instead of NOTE?

OK ...as verified by others in yesterday's meeting, master has the problem and the fix is good. I'm not sure what planet my system was on when I could not repro the problem in master on Sunday.
