Controls_Manager::add_tab Stops Working with 2.9.0

[meceware]

Hi,

Starting from 2.9.0 (beta5), Controls_Manager::add_tab stops working. Page Settings tabs cannot be routed.

The tab can be added and shown without problem with this code.

use Elementor\Controls_Manager;

// Called from 'elementor/init' action
Controls_Manager::add_tab( 'my-tab', 'My Tab' );
      add_action( 'elementor/element/wp-page/document_settings/after_section_end', array( $this, 'after_section_end' ), 10, 2 );

public function after_section_end( $page, $args ) {
  print_r(Controls_Manager::get_tabs());

  $page->start_controls_section(
    'my-tab-activate',
    array(
      'label' => 'My Tab Label',
      'tab' => 'my-tab', // NOT WORKING
      // 'tab' => Controls_Manager::TAB_SETTINGS, // WORKING
    )
  );

  $page->add_control(
    'my-tab-enabled-disabled',
    array(
      'label' => 'Enable',
      'type' => Controls_Manager::SWITCHER,
      'default' => 'no',
      'label_on' => 'Yes',
      'label_off' => 'No',
      'return_value' => 'yes',
    )
  );

  $page->end_controls_section();
}

This code is working with 2.8.5 however starting from 2.9.0, the page receives the error below and the tab cannot be shown. The error is received when the tab is clicked.

Is there any other way to add tabs to Page Settings?

I'm still experiencing the same issue in Elementor 3.3.0.

The issue happen only if the built-in "Content" tab is not defined and we use custom tabs.

When the "Content" tab is defined, it's possible to display a custom tab. If there is only custom tabs however, we will run into the "Routes: panel/editor/custom-tab-name" error when trying to access it.

It looks like it's an issue with the default tab, which apparently can only be a built-in one (like "Content" or "Advanced") currently
