Delete zone need to be reseted after page tree resize

[dkoether]

Hello everyone,

i found a bug in addition to this extension. When you select a page without subpages and then resize the page tree the delete zone for the drag and drop delete feature is shown. Since the basic TYPO3 page tree is not responsive anymore (boooh :() the red delete zone's position wont be recalculated.

Thanks for bringing better TYPO3 backend experience back with this extension!

Best regards!
