Link picker doesn't work for experience page folders

Hi Team ,
Issue :
If we mention node-type as “hippostd:folder”  while creating document-type in cms v15.2.3 & v15.3.0 and above versions then the Link picker doesn’t work for experience page folders(OK button is disabled)

We suspect that the issue is happening due to recent changes in code , please refer CMS-13987.

Current workflow :
LinkPickerDialog class in the isValidSelection() method has Xpageselction boolean variable and it is returning false value and it pass the boolean value to isDocumentAllowedInFolder() method.

Code suggestions: 
If we set Xpageselection boolean value as true and pass it to isDocumentAllowedInFolder() method
Then we are able to select the experience folder in the linkpicker dialog box.
