title: What is `Can't find variable: loadHomepageTiles` error on iOS 11.3
body: <p>I recently came across this error <code>message: Can't find variable: loadHomepageTiles</code> on our error logs from one of our angularjs 1.6 mobile applications.</p>
  
  <p>This seems to only happen on iOS devices running 11.3 based on the error logs.</p>
  
  <p>We don't have any reference to <code>loadHomepageTiles</code> on our codebase and I could not find any references to this in any of the node modules either so. It seems to be generated by mobile safari from what we can tell.</p>
  
  <p>I can't seem to find any documentation about it on the net or how to recreate the error on an iOS device. Does anyone have any experience with this error? or could point me towards any documentation, please? thanks</p>
