Extending a Button with FileDownloader causes any keyboard shortcut added with setClickShortut to not work

[mpittkin]

Found using Chrome, Vaadin 8.4.3, Wildfly 10.1

To reproduce create a Button and add a keyboard shortcut using something like:

Button btnDownload = new Button(VaadinIcons.DOWNLOAD, event -> System.out.println("download")); btnDownload.setClickShortcut(KeyCode.P, ModifierKey.CTRL);

The button (if you added a click listener) is triggered when you click it or press Ctrl-P. Then take out the click handler and extend with FileDownloader:

Button btnDownload = new Button(VaadinIcons.DOWNLOAD); btnDownload.setClickShortcut(KeyCode.P, ModifierKey.CTRL); StreamResource downloadResource = getDownloadResource(); FileDownloader fileDownloader = new FileDownloader(downloadResource); fileDownloader.extend(btnDownload);

The download works if you click the button, but it no longer works if you press Ctrl-P.

FileDownloader is hooked at the browser level, so the shortcut doesn't work, but the clickEvent is triggered when you click on the button or use the shortcut, its only the file download that is not triggered on using the shortcut. I think that is more of a missing feature than a bug. If there is need for that I would suggest creating a new issue requesting the feature of shortcut support on FileDownloader.
