I have hit a variable problem when using animations to show groups when working with responsive widths. A straightforward show works fine but when using any animation there appears to be a risk that some groups will not make full use of the width available. Interestingly, if I am running the app with the dev tools in place and I make any adjustment to screen width, the groups immediately respond out to the expected size.
Easy work around is just not to use animations when dislaying a group, but I would like to use them if this problem could be resolved.
