There was a bug on iOS where the fontsize of the native text inputfield didn't match the size of the JavaFX TextField in case a custom font size was used, or in case the component or one of its parents was scaled.
This has been fixed by https://bitbucket.org/javafxports/8u-dev-rt/commits/5e2574434d5a63079e6398145d663ed483401bb3 I can create an issue on bugs and submit the patch there as well? However, it seems to me the _requestInput method on Window is only really used on iOSWindow. All the others (MonocleWindow,...) throw an UnsupportedOperationException. The patch above modifies the signature of the _requestInput method on all implementation classes, which is a bit silly as those methods are never used. Another option is to make _requestInput non-abstract with a void implementation, and override it on iOSWindow? - Johan
