What Happened?

When creating a 'Media' field and setting it to be shown in the backend, the raw media url is shown. The default admin list view uses the 'escape' function to render the field content

This function limits the value to 50 characters, and media fields are saved with lots of extra parameters, for example

Full url: images/Logos_Images/site_logo.png#joomlaImage://local-images/Logos_Images/site_logo.png?width=488&height=132.
If i wanted to show the image in an tag instead of the raw url, this would be shortend to 50 chars since the escape function has that as default.

This results in an empty string

Steps to reproduce the Bug

Create Media field
Add it to admin view and set to show in list view
Add custom code in 'getItems after all'
Logo is no longer shown

There is an option in the field settings that, when enabled, prevents the field’s value from being escaped where it is used. Enabling this option may resolve the issue. It is not ideal, but it is the current workaround.
