Hi,
I recently came across a problem with showModalDialog in Safari 11.0. I am not able to open two modal dialog simultaneously using showModalDialog, the second one does not open any dialog and the return value is always 'undefined'.
Here is an example:

The same code opens up two dialog in IE-11 but only one in Safari 11.0.
Any idea on the reason for this discrepancy? Thanks in advance.
