Closing Panels Reverts to Main Page on iOS 11.2.5

[aesculus]

I recently updated my device to iOS 11.2.5 and any panel that goes Back causes subsequent panel closes to revert to the main menu.

Sometimes it takes two taps to cause the Back button to action and then the issue shows up for subsequent dialog loads where closing them results in a return to the main panel.

It appears that iOS 11.2.5 Safari has made some changes on how it caches or deals with returning to panels. It seems like the history is being corrupted.

Anyone have any experience with this?

An update to this: It appears to be an incompatibility with Google Maps API 3.31.

I forced the API to API V3.30 and all is OK.

I should have suspected this when I recently had to change a CSS hack to deal with an InfoWindow format problem.
