shortcut of "Go to OSM wiki for tag help" not reassignable

[Klumbumbus]

What steps will reproduce the problem?

1. right click on a tag in the tag/membership dialog
2. see how "Go to OSM wiki for tag help" has F1 as shortcut
3. "Go to OSM wiki for tag help" is not reassignable in the shortcut preferences

Please provide any additional information below. Attach a screenshot if possible.

Background:
I reassigned copy to F1, paste tags to F2 and Help to F4. If focus is the tags/membership dialog copying of objects with F1 does not work as "Go to OSM wiki for tag help" kicks in which is still on F1.

Indeed:

public class HelpAction extends AbstractAction {
...
    public HelpAction(JTable tagTable, IntFunction<String> tagKeySupplier, IntFunction<Map<String, Integer>> tagValuesSupplier,
            JTable membershipTable, IntFunction<IRelation<?>> memberValueSupplier) {
...
        putValue(NAME, tr("Go to OSM wiki for tag help"));
...
        putValue(ACCELERATOR_KEY, getKeyStroke());
    }

    /**
     * Returns the keystroke launching this action (F1).
     * @return the keystroke launching this action
     */
    public KeyStroke getKeyStroke() {
        return KeyStroke.getKeyStroke(KeyEvent.VK_F1, 0);
    }
...
public class PropertiesDialog extends ToggleDialog
...
    /**
     * Assigns all needed keys like Enter and Spacebar to most important actions.
     */
    private void setupKeyboardShortcuts() {
...
        // F1 button = custom help action
        getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(
                helpAction.getKeyStroke(), "onHelp");

In 15644/josm:

fix #18091 - reuse Help shortcut inside tag/membership dialog

Thanks. That simplifies my workflow.
