Lost support for Safari 10
Steps to reproduce
Use iPad 4 (running iOS 10.3.3) or Firefox 48 on Mac OS X 10.7 to look at foodsharing.de (or .at or foodsharingschweiz.ch), also beta.* Other older browsers might be affected as well. Interestingly, on iPhone 4 with iOS 7, the frontpage loads correctly.
What is the current bug behavior?
What is the expected correct behavior?
The carpet roll should be shown, and the mobile navigation should function.
Going back through the commit history of master, I could identify that the problem did not exist yet in commit bab085d6 and was introduced by @nicksellen in of the 18 commits between 0983d95b (which runs into a Whoops! exception) and 25b59d46 (being the first commit that shows the frontpage normally on Firefox 60, but not on Safari on the iPad 4). Note: the first few commits run into a Whoops, but from 35bd867b onwards, neither old or modern browsers show the frontpage. Therefore the bug must have been introduced in these 18 commits.
EDIT: this issue has previously been named
Lost support for older browsers
