Does Playwright have some special async handling for the page.on listener? If not, this will cause an unhandled rejection if the evaluate throws. Plus AFAIK page.on does not return a promise, so the Promise.all is redundant.

closes #1336
JQuery requires the global
documentobject, which is not available whenPage.addInitScript-s are added. This solution, therefore, introduces the newinjectFileoptionwaitForDOM, which ensures the script does not get injected until the DOM load.The implementation of
waitForDOMneeds rework. Loading bigger scripts (as JQuery, for instance) takes a longer time and introduces "race condition," as there is no way of waiting for the script load to finish. This makes testing + usage a guessing game.
