Unnecessary redeploys by "deploy on save"

### Apache NetBeans version

Apache NetBeans 23

### What happened

Working and making changes on different files and jumping from one file to another one sometimes triggers a webapp redeploy even though when no file has been saved at all.
This is a problem because Wildfly, Tomcat and Glassfish run out of PermGen after 10 or so redeploys.
The webapp should only redeploy when changes has been saved. Or am I misunderstanding this feature?

### Language / Project Type / NetBeans Component

Java maven project

### How to reproduce

Reproduceable with any maven webapp.

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

ubuntu 24.04

### JDK

openjdk 17

### Apache NetBeans packaging

Apache NetBeans Snap Package

### Anything else

_No response_

### Are you willing to submit a pull request?

No

Start by reproducing the unnecessary redeploy with a Maven webapp while switching between unsaved files, then trace the NetBeans deploy-on-save behavior involved in the webapp workflow. Verify the change by confirming that switching files without saving causes no redeploy, while saving a changed file still does.
