fix (AIQ-4414): w/ add stopPropagation to prevent closing modal if Esc pressed inside MultiSelect

[GlebShchipanov]

It looks for me that this stopPropagation wouldnt break anything, but if anyone have any concerns - please comment

Also i found that case MenuActions.CloseSelect right above my changes never fired, anyone know anything about this? Maybe we can remove that excessive part?

Tested on Storybook and confirmed that this change doesn't seem to negatively impact any existing functionality.

stopPropagation can often have unintended consequences, but this seems like an example of a case where it is appropriate to use.

I'm going to approve, but @GlebShchipanov please wait a day or so to merge to give others an opportunity to provide feedback.

From the code, it looks like CloseSelect applies when the user presses 'alt' and the arrow up key - from source/shared.ts:

} else if (key === Keys.Up && altKey) {
			return MenuActions.CloseSelect
		}
