Lister: title label on one template affects all filter rows

[Toutouwai]

Short description of the issue

I have two templates, one where the title field has been relabelled and one where it has the default field label:

The page structure is that the child page has "my_template" and the parent page has "my_parent_template".

I have Lister configured as below (typically this would be done via a Lister Pro config but this is to demonstrate that the issue is with ProcessPageLister).

$wire->addHookBefore('ProcessPageLister::execute', function(HookEvent $event) {
    /** @var ProcessPageLister $lister */
    $lister = $event->object;
    $lister->useColumnLabels = true;
    $lister->initSelector = 'template=my_template';
    $lister->defaultSelector = 'title%=, parent.title%=';
});

Note how the title field label for my_template seems to be affecting all title fields that are used in the Lister filters. The problem doesn't occur in the column labels.

For a parent.title filter I don't expect that Lister could detect a relabelled title field (if that had been done) because the parent template could be anything, but it should just show the default label of "Title" because the custom title label for one template won't make sense for other templates.

Setup/Environment
