CodePen Demo which demonstrates the issue:

https://codepen.io/vadymchyk/pen/yLyOOPX

Detailed Reproduction Steps:

Create two multiple dialogs
First:
clickOutsideToClose: false,
escapeToClose: false,
Second (nested):
clickOutsideToClose: true,
multiple: true,

1. Open the first dialog
2. Open the second dialog(multiple)
3. Press "Esc" or click outside when the second dialog is opening (during animation)

What is the expected behavior?

The first dialog stay opened

What is the current behavior?

The first dialog is closed

What is the use-case or motivation for changing an existing behavior?

Which versions of AngularJS, Material, OS, and browsers are affected?

• AngularJS: 1.7.8
• AngularJS Material: 1.1.20
• OS: all
• Browsers: all

Is there anything else we should know? Stack Traces, Screenshots, etc.

Did you change something with your CodePen reproduction after posting it? When I test it in Chrome Version 79.0.3945.88 or Firefox 70.0.1 on macOS, I see the first dialog stay opened as you expected.

I have not changed anything. The bug is still reproduced:

Thank you for sharing the video. I'm not able to reproduce that behavior.

Are you on Windows?

What browser and version are you using?

[Vadymchyk]

Reproduced on macOS 10.15.2:
Google Chrome Version 79.0.3945.88 (Official Build) (64-bit)
Safari Version 13.0.4 (15608.4.9.1.3)

and I saw this bug on Windows machine too.

OK, I can reproduce this if I do this critical part of the reproduction steps

when the second dialog is opening (during animation)

The ESCAPE shouldn't close the first dialog with escapeToClose: false, but it does. This does certainly seem like a buggy edge case.
