Opening webDAV folder-as-workspace does a recursive find every folder/file which causes a hang until its finished

Description of the Issue

Hangs on opening

Steps to Reproduce the Issue

1. Start notepad++

Expected Behavior

open as usual

Actual Behavior

hung, white screen, but name of a "webDAV" folder file was on the window

• closed notepad++ and repeated several times - still hung
• on webserver, deleted the .DAV folder - still hung
• on PC, navigated to the file in windows explorer and opened it - worked fine - notepad++ still hung
• opened from cmd.exe with -noPlugin => still hung
• opened with -nosession => opened OK
• did 'open folder as workspace' and selected the webdav parent folder => hung again
  => will try rebooting PC and trying again
  => even if a windows issue, notepad++ should time out after (say) 30 secs
  => after (say) 3 hangs in a row, do -noplugin -nosession

Start by reproducing the hang with a WebDAV parent folder using Open Folder as Workspace, then compare behavior with -nosession and -noplugin. The issue provides no source file or test entry point; done means the folder can be opened without an indefinite hang and the reported WebDAV case is covered by a clear regression check.
