UX Overflow content hidden if screen width too narrow

[raissanorth]

When opening the security report (through the CMS' Reports navigation) on a window/tab with narrow screen width, the overflow content is hidden and can not be accessed by other means than extending the screen width.

silverstripe/securityreport               dev-master 24a71d6

silverstripe/framework                    4.1.x-dev 9ed3cd4
silverstripe/cms                          4.1.x-dev 7dea009
silverstripe/reports                      4.1.x-dev ac23686

Note that in contrast in CWP 1.8.1 a horizontal scroll bar gets added, so the relevant content is still accessible.

Ok this looks like an issue for GridField itself, and should be logged on framework. It could perhaps be the same as this issue? silverstripe/silverstripe-framework#3742

I'm going to close this as a duplicate of that for now, since resolving that issue would fix this issue too.

I have reproduced the fact that this is a regression from CWP 1.8, however, and have noted this on that issue.
