Bring in line with PsychoPy by accepting arguments as follows:
(a) mouse.isPressedIn({"shape": myStim, "buttons": 1})
(b) mouse.isPressedIn(myStim, {"buttons": 1})
(c) mouse.isPressedIn(myStim, 1)
Insert a `refresh()` method into the `Slider` component to
switch on the `_needVertexUpdate` property so that resizing
the `Window` properly reflects on instance position.
Leaving the elements means that a user can press enter to submit the form. Since there is no action="..." attribute, will default to submitting the form to the current page, effectively causing a page reload. Because the intention is for the user to proceed by pressing the 'Ok' button on the jQuery dialog, this only causes an annoyance to the user.
Ensures dialogs are immediately removed from DOM when closed.
Previously, dialogs were destroyed but not removed causing possibility of duplicate element IDs, so jQuery unitentionally selects and recreates old dialogs, thus GUI._updateOkButtonStatus updates the wrong button.
Old behaviour of ._downloadRegisteredResources attempts to download all registered resources, regardless of whether they have been previously downloaded. howler.js appears to ignore requests to re-download, however PreloadJS will redownload, which can cause critical errors if a resource is being used while being unnecessarily redownloaded
Now use a Map to keep track of individual elements to prevent duplication.
Previously would increment continuously just by switching dropdown options. So users could bypass the requirement to complete starred(*) fields by toggling a dropdown a few times, or by focussing and unfocussing input elements, causing nbSetRequiredKeys++ to increment without limit.
GlobalEventHandlers.onchange only fires when focus is lost. However .oninput fires whenever contents are modified. Original requires "double click" behaviour: first click to deselect the input element, second click to actually click the "Ok" button. Old code results in "Ok" buttons remaining visually disabled thus confusing users even when input elements have been completed
