In previous versions of Pickr, catching exceptions during Pickr creation
was sufficient to detect whether Pickr can be used with the current
browser. This is no longer the case, and we must instead rely on the
lack of an "init" event.
This is particularly important for AngularJS 1.8.x and jQuery 3.5.0+,
which will no longer correct this automatically with their HTML
prefilters, resulting in unexpected nesting of tags when the browser
interprets something like "<div/>" as "<div>" (older versions of jQuery
would have corrected "<div/>" to "<div></div>").
