Make Categories full height.

First, awesome plugin!
I was looking to this to make.
Especially this option => Taxonomy(Categories) In-field search – Adds a search field after the taxonomy title that filters the list below

Unfortunately I bump into a small issue. I had this code, in my child theme function.php to make the categories box height to 100% instead of the scrolling sidebar. Now this seems not to work any more.

This is the code I’m using for the default wp. Can you assist me to solve this issue, so it also works again with your plugin. Thank you in advance.

// Make the categoires box bigger in the admin.
add_action(‘admin_head’, ‘admin_taller_categories_box’);

function admin_taller_categories_box() {
echo ‘<style>
.categorydiv div.tabs-panel {
max-height: 100%;
}
</style>’;
}
