Description Richard Mah CLA 2011-05-05 17:26:59 EDT 
Build Identifier: 3.6.2

I'm seeing an extra SWT.FocusOut event when I click on the "down arrow" of the combo to reveal it's list.  I'm only seeing this on Linux.  On Windows, I'm seeing the SWT.FocusOut event only when I click off of the combo (which is the expected behavior).

I'm using the combo to edit a cell in a table.  Below is an SWT sample which shows how the combo is being used.  The sample is using a Text but the usage is the same:
http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet124.java?view=co

The extra SWT.FocusOut causes the combo to be disposed when it shouldn't be.  This causes Eclipse to hang on SLES 11.1 and operate improperly on RedHat 6.0

Reproducible: Always

I can reproduce the issue on SWT master, GTK3.22, and Fedora 28.
