Disabled tabs able to be navigated to in some conditions

[Jason Rodriguez]

When using the SfTab component, disabled tabs can still be selected under certain conditions:

• Via Hotkey (Using toolbelt.hotkey library): A hotkey mapped to a disabled tab will activate it, allowing the tab’s content to be shown even though it is marked disabled.
• On Page Load: If the disabled tab is set as the selected index on initial load, the tab will be activated and displayed.
• Via Button Click (Programmatic Navigation): Triggering tab selection through code or an external button click will also navigate to disabled tabs.

Expected Behavior:

• Disabled tabs should not be selectable or displayed through any interaction method (keyboard, programmatic, or initial load).

Actual Behavior:

• Disabled tabs can be navigated to and displayed, which breaks the expected disabled state.

Steps to Reproduce:

• Create an SfTab with two tabs: one enabled, one disabled.
• Attempt to select the disabled tab using: A hotkey, Page load with SelectedItem or SelectedIndex set to the disabled tab, and A button click that programmatically sets the disabled tab as selected.
• Observe that the disabled tab becomes active and its content is displayed.

Impact:

This undermines the purpose of disabling a tab. It may allow users toA navigate into sections of the UI that should remain inaccessible.

Code Sample:

Attached is a text file with a code snippet you can use to repro this as well it shows selection of a disabled tab through onload, hotkey and button click
