If you generate a Checkboxradio from a checkbox/radio with a label that
contains encoded HTML, e.g. `<em>test</em>` this will work fine
at first. If, however a refresh is triggered on that instance (explicitly or
e.g. by turning it into a `Controlgroup`), the previously escaped HTML will
now be evaluated.
If the label was created based on some user input, this could lead to
unexpected code execution even though the initial output was escaped.
Fixes gh-2101
Closes gh-2102
This helps fix issues that make tooltip tests sometimes fail when run against
jQuery 3.2 or newer due to timing differences.
Details:
* Add the `moduleAfterEach` function ensuring no timers are running.
* Attach this function via `common.testWidget`.
* Attach this function to most test suites.
* Add a tooltip test helper cleaning up leftover timers.
* Rename legacy `setup`/`teardown` hooks to `beforeEach`/`afterEach`.
Closes gh-1920
