I can confirm using 17.10 that an unresponsive window does not freeze
the shell, but it does freeze the window's controls and blocks moving
the window etc.
I wonder if you are getting a whole shell freeze or just the app window
(which might feel like the whole shell if it's large). When the problem
occurs, can you tap Super to get to the activities overview?
I'm thinking if you are getting a whole shell freeze then this might be
something that has been fixed between Ubuntu 16.04 and 17.10.

Title:
Unresponsive windows freeze the whole shell
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
When an application becomes unresponsive, the whole shell gets frozen.
The expected behaviour would be that the shell continues to be
responsive when a single application stops responding, possibly
notifying the user that a window is not responding.
This is happening to me quite frequently, when using Inkscape. At some
random point Inkscape freezes because of a crash, but instead of being
closed, it remains open keeping the whole shell frozen.
The only workaround I could find to resume working has been to move to
another tty, killall inkscape, and then switch back to the graphical
shell.
