$lazy_sources triggers a undefined variable PHP notice

[DahmaniAdame]

Undefined variable: lazy_sources in Image.php on line 273

We need to either move $lazy_sources = 0; outside of if ( preg_match_all()){} or move if ( 0 === $lazy_sources ){} inside of if ( preg_match_all()){} (like we do on WP Rocket).

Lines 259 to 275 in 4332a0d

	if ( preg_match_all( '#<source(?<atts>\s.+)>#iUs', $picture['sources'], $sources, PREG_SET_ORDER ) ) {
	$sources = array_unique( $sources, SORT_REGULAR );
	$lazy_sources = 0;
	foreach ( $sources as $source ) {
	$lazyload_srcset = preg_replace( '/([\s"\'])srcset/i', '\1data-lazy-srcset', $source[0] );
	$html = str_replace( $source[0], $lazyload_srcset, $html );
	unset( $lazyload_srcset );
	$lazy_sources++;
	}
	}
	if ( 0 === $lazy_sources ) {
	continue;
	}
