Inconsistency: \Magento\Catalog\Block\Adminhtml\Product\Edit\Tab\Attributes::_getAdditionalElementTypes() fires the event «adminhtml_catalog_product_edit_element_types» but \Magento\Catalog\Block\Adminhtml\Category\Tab\Attributes::_getAdditionalElementTypes() does not fire a similar event

Method \Magento\Catalog\Block\Adminhtml\Product\Edit\Tab\Attributes::_getAdditionalElementTypes() allows an extension to add custom element types to admin product page by handling adminhtml_catalog_product_edit_element_types event:

magento2/app/code/Magento/Catalog/Block/Adminhtml/Product/Edit/Tab/Attributes.php

Line 151 in 0be91a5

$this->_eventManager->dispatch('adminhtml_catalog_product_edit_element_types', ['response' => $response]);

A similar method for categories \Magento\Catalog\Block\Adminhtml\Category\Tab\Attributes::_getAdditionalElementTypes() needs to do so too.

magento2/app/code/Magento/Catalog/Block/Adminhtml/Category/Tab/Attributes.php

Lines 124 to 130 in 0be91a5

	protected function _getAdditionalElementTypes()
	{
	return [
	'image' => 'Magento\Catalog\Block\Adminhtml\Category\Helper\Image',
	'textarea' => 'Magento\Catalog\Block\Adminhtml\Helper\Form\Wysiwyg'
	];
	}

Now an extension can add custom element types to admin product page, but can not do so for admin category page.

My workaround solution: https://mage2.pro/t/148
It is not perfect because it overrides a core class, but I have not found a more proper solution.
