The table is not created when I press ok button

Only reproduced on Chrome ( tested on Version 67.0 ). Works on Firefox ( tested on Quantum 60 )

Steps to reproduce:

1. Open in edit mode the Home page ( Main.WebHome )
2. Clicked directly on "Table" button from the toolsbox, without having the focus on edit textarea
3. The Table Properties appears
4. When I press "ok" button nothing happens

Expected result: the table should have been created at the beginning of the page

I does work if I have the focus on the textarea or if I do it from Firefox
