It looks like bulk product updates don’t use the Magento\Catalog\Api\ProductRepositoryInterface when saving product data. You can see in the queue consumer Magento\Catalog\Model\Attribute\Backend\Consumer::execute() that it is calling Magento\Catalog\Model\Product\Action::updateAttributes().

You didn’t specify what your plugin does, but maybe you can create an observer on the event catalog_product_attribute_update_before which gets emitted during that call chain I mentioned above.
