Eclipse Hover loses control in certain cases

[mehmet-karaman]

Steps to reproduce

From a fresh installation and clean workspace:

• Create a new Java Project and open a java class in the java editor
• Move the mouse to a place where the hover shows up. (eg. Class head and hover on the class name)
• Double click on the Hover
• Minimize the Eclipse window and show it back.
• Move any other applications window to the foreground
• The hover is still visible above the foreign windows

I expected:

The Sticky hover shouldn't be visible (closed when focus is lost)

But got:

Sticky hover is still there

Tested with Eclipse Version:

Version: 2024-12 (4.34)
Build id: I20241022-1800

Here is a video recorded in windows:

Reproducible with latest 4.34 RC2 on RHEL 9.2 too, so this is not Windows specific.
