Problem/Motivation
When editing an H5P object I am seeing the following code deprecation warning at the moment of hitting the submit button...
Deprecated function: Constant FILTER_SANITIZE_STRING is deprecated in H5peditorFile->__construct() (line 14 of vendor/h5p/h5p-editor/h5peditor-file.class.php).
