Textselection rules should be context dependent

### Apache NetBeans version

Apache NetBeans 23

### What happened

Hello, there is a flaw from version 21 to 23 that in version 20, when selecting an identifier id # in the javascript file, it selects all text (name and #)
But if it is javascript in a php file, it only selects the text, not the #.
How can I fix

Start by reproducing the reported identifier selection in standalone JavaScript and JavaScript embedded in a PHP file on NetBeans 23, comparing it with the reported NetBeans 20 behavior. Trace the editor's context-dependent selection handling; done means the selection consistently follows the intended rule in both contexts and the regression is covered by a test.
