Hi

I have found a way to reproduce this problem.

1) Create a DocumentEditorContainerComponent

2) Use the toolbarItems property on the container and add Images and/or Break (which contain a DropDownButton)

3) Destroy the DocumentEditorContainerComponent

4) When you make a mousedown anywhere on the page you get this error :

drop-down-button.js?e7e7:397 Uncaught TypeError: Cannot read property 'querySelector' of undefined

    at DropDownButton.removeCustomSelection (drop-down-button.js?e7e7:397)

    at Observer.eval (drop-down-button.js?e7e7:504)

    at Observer.notify (observer.js?811a:84)

    at DropDownButton.Base.trigger (base.js?3923:181)

    at DropDownButton.closePopup (drop-down-button.js?e7e7:501)

    at DropDownButton.mousedownHandler (drop-down-button.js?e7e7:444)

Hi Steven, 

We couldn’t reproduce the reported scenario. Kindly check the below stackblitz sample and modify the same sample to reproduce the reported scenario in our end. It will be helpful for us to provide solution at the earliest.

Hi Harini,

You can reproduce with this stackblitz sample https://stackblitz.com/edit/react-5q3sns-yozc36

1) click on the close button under the document editor

2) click anywhere on the page

After you can even try to do any modification in the code to make the page Hot Reload and after the document editor is displayed wherever you click on the page you'll get the error.

It look like there is a listener onMouseDown not being removed when removing the document editor from the page.
