Deprecation: #95351 - Custom JSWindow options in HMENU settings

See Issue #95351

Description

The common HMENU settings for each HMENU level JSWindow (including subproperties) and target with a value such as target = 200x300, to be set on e.g. TMENU properties have been marked as deprecated.

Examples:

page.123 = HMENU page.123.1 = TMENU page.123.1.JSWindow = 1 page.123.1.JSWindow.params = width=200,height=300,status=0,menubar=0

page.123 = HMENU page.123.1 = TMENU page.123.1.target = 200x300

Impact

Calling a frontend page with a HMENU and JSwindow popups will trigger a PHP deprecation warning.

Affected Installations

TYPO3 installations with a HMENU and JSwindow settings which are configured via TypoScript, which is highly unlikely in 2021.

Migration

Use an external JavaScript file with an event listener to achieve the same functionality.
