           Summary: <input type="file">:  click() doesn't trigger an file
                    upload dialog while using an angular entry component
                    (materals MatBottomSheetRef)
           Product: WebKit
           Version: Other
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal

         Component: DOM

I tried to trigger a click event on an input element with type "file" after an entry component was closed. But in a browser with WebKit Engine this doesn't work.

I have prepared an example on StackBlitz!

The result: https://angular-wdnpmb.stackblitz.io

In a WebKit-Browser: Click on the button "should open modal". A modal appears on bottom. Click on "file upload" but no file upload dialog appears!

The very simple and clean code: https://stackblitz.com/edit/angular-wdnpmb?embed=1

If you debug you can see that every thing is fine. The line 15 in app.component.ts is proceed correctly.
