$wgImageLimits = array(
	array(320,  3000),
	array(640,  3000),
	array(800,  3000),
	array(1024, 3000),
	array(1280, 3000),
	array(1600, 3000),
	array(1900, 3000)
);
I want limit only images widths, so I setted all heights to 3000. Now if image height less than 3000 then "Other resolutions" on image page (like https://www.mediawiki.org/wiki/File:Astronotus_ocellatus.jpg) is not displaying (only original size), because of this part in ImagePage.php https://github.com/wikimedia/mediawiki-core/blob/a3983418d5748fbccdda15e0e48af90c50ef1f67/includes/ImagePage.php#L386:

						if ( $size[0] <= $width_orig && $size[1] <= $height_orig
							 && $size[0] != $width && $size[1] != $height
						) {
							 $sizeLink = $this->makeSizeLink( $params, $size[0], $size[1] );
							if ( $sizeLink ) {
  								$otherSizes[] = $sizeLink;
							}
						 }

If one of this rules not true, size not included:
$size[0] <= $width_orig // if width from $wgImageLimits less than origin
$size[1] <= $height_orig // if height from $wgImageLimits less than origin
$size[0] != $width // almost always true
$size[1] != $height // almost always true

But size should be not included only if width OR height less than origin. So hotfix will be:

						if ( ( $size[0] <= $width_orig || $size[1] <= $height_orig )
							&& $size[0] != $width && $size[1] != $height
						) {
							$sizeLink = $this->makeSizeLink( $params, $size[0], $size[1] );
 							if ( $sizeLink ) {
								$otherSizes[] = $sizeLink;
							}
						}
