Suggestion to Add PHPDoc Block for twenty_twenty_one_can_show_post_thumbnail Filter

[viralsampat]

Hello Team,

While reviewing the theme files, I noticed that the twenty_twenty_one_can_show_post_thumbnail filter currently lacks a PHPDoc block.

Adding a proper PHPDoc comment would improve code clarity and enhance the overall documentation, making it easier for developers to understand and utilize the filter effectively.

Thanks,

I have checked above mentioned issue and resolved it. Here, I have added my patch.

The twenty_twenty_one_can_show_post_thumbnail filter already has a correct docblock:

	/**
	 * Filters whether post thumbnail can be displayed.
	 *
	 * @since Twenty Twenty-One 1.0
	 *
	 * @param bool $show_post_thumbnail Whether to show post thumbnail.
	 */

It sets the $show_post_thumbnail conditions within apply_filters(), not in a separate line.
