The documented values that jQuery.attr() accepts are String, Number, or
null. For some reason, when we pass a Boolean value, the subsequent
click handler does not work in some situations.
Changing this to take a Number, and unsetting it when empty, resolves
this issue.
The accessibleChange custom interaction event was only listening for
blur and focus, however some OS/browser combinations do not emit these
events until the element is explicitly blurred. This is notably
different on Firefox on some Operating Systems.
Recent changes in MDL-68167 explicitly moved the user participants page
filter module to use the accessibleChange event, which means that the
selections are now only triggered on an explicit blur when using
Firefox. This highlight a bug whereby, when the mouse is used to make a
selection, the event is not triggered until the element is blurred.
This change modifies the accessibleChange event to ignore the `change`
event where it was triggered by the keyboard and where that keybaord
event was not a [return] or [escape] keypress, but to otherwise respect
the native change event.
The `blur` event does not bubble, but the `focusout` events are not
available in all supported versions of Firefox.
Rather than switching event, this patch using event capture to
effectively achieve the same result and bubble the event up through the
DOM to the delegated listener.
There should be no functional change with this patch, except to support
Firefox fully.
With MariaDB 10.2.7 the driver was incorrectly returning '' (empty
string) as default for all the columns having null (meaning, no
default).
Also, cover the case in unit tests, it seems that we were already
testing other defaults but not the null case.
The content of the autocomplete selection div is purged by javascript
so we have to move its label outside of it. aria-labeledby is the way
to go.
Each time the suggestion box is expanded, autocomplete js renders the
autocomplete suggestions template. So the label cannot be outside the
suggestions ul.
* With the removal of the label element, Behat now has to click on the
answer text. In order to achieve this, the custom partial named selector
"qtype_multichoice > Answer" was now added and have replaced the
instances where the label of the answer's checkbox/radio button is
being clicked.
* Discard the use of the label element in order to be able to render
multiple choice answers as they are and have these act as the radio
button/checkbox' label through the aria-labelledby attribute.
* New JS module qtype_multichoice/answers that listens for click events
on the answer text container and selects the appropriate answer radio
button/checkbox.
