Very slow manual upload with PHP project

### Apache NetBeans version

Apache NetBeans 13

### What happened

In PHP project using remote connection with SFTP upload working extremely slow with "Manually" upload feature,
while "On Save" upload works fine.
When doing manual upload the connection is established immediately but file
upload starts after more than 20 seconds and longer.
Time delay depends of number of files and directories in project. It's look that ftp make scan of all directory tree.

It seem that is old unresolved issue that is described in details here:

### Code of Conduct

Yes

Start by comparing the manual and On Save upload paths for PHP projects using remote SFTP, then read the linked Bugzilla report 269601 about the directory-tree scan. Done means manual upload no longer waits over 20 seconds before starting while On Save behavior remains working; no reproduction steps or test entry point are named in the issue.
