Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

No response

Description

this.clipBoard.copy('copy text') is not working in Chrome. It always return false when its inside the observable and the response of the observable takes more time. This same scenario works fine when I tested in IE. There are not warnings/error in browser console.

I have also tried with beginCopy/copy/destroy methods but it didnt get copied and no errors in browser console.

There are other places I have used the copy method inside observable and it works fine. The difference in this observable is it returns the observable response faster than the one which doesn't work.

Reproduction

 onSubmitClick() {
    this.statusMessage = 'Processing, please wait...';
          const inputParam = new UIInputVO();
          this.service.generateOutput('inputType', inputParam).subscribe(
            (response: any) => {
              this.statusMessage = response.resultMsg;
              this.txtOutputList = response.txtOutputInfo;
              this.clipBoard.copy(response.windowsPath);
              if (!this.btndisabled) {
                  setTimeout(() => {
                      // this will make the execution after the above boolean has changed
                      this.submitbtn.nativeElement.focus();
                  }, 0);
              }
            }
          );
  }

Expected Behavior

It should copy to user clipboard

Actual Behavior

not copied the string passed to copy method
