Comment:

 Hi @pelstudio, welcome to Trac and thanks for opening this ticket!

 As this was introduced in 5.3.1, I'll update the `Version` property to
 note when this first became an issue.

 It looks like we could change [https://github.com/WordPress/wordpress-
 develop/blob/trunk/src/wp-admin/includes/image.php#L261 this condition]:

 {{{#!php
 <?php
 if ( $imagesize['mime'] !== 'image/png' ) {
 }}}

 to:
 {{{#!php
 <?php
 if ( 'image/png' !== $imagesize['mime'] || apply_filters(
 'big_image_scale_png', false, $imagesize, $file, $attachment_id ) ) {
 }}}

 @azoazz What do you think about this?
