Summary of Changes

Fixes inline assets in module with Progressive Caching enabled.

Testing Instructions

Add some inline scripts and styles to a module:

$app->getDocument()->addStyleDeclaration('* {background:white !important;');
$app->getDocument()->addStyleDeclaration('* {background:black !important;');
$app->getDocument()->addStyleDeclaration('* {color:white !important;}');
$app->getDocument()->addStyleDeclaration('* {color:white !important;}');
$app->getDocument()->addScriptDeclaration('alert(1);');
$app->getDocument()->addScriptDeclaration('alert(2);');
$app->getDocument()->addScriptDeclaration('alert(1);');
$app->getDocument()->addScriptDeclaration('alert(2);');

Enable Progressive Caching.
View some page twice to generate cache and to load cached data.

Expected result

No warnings.
The added styles/scripts are working correctly.
Duplicated scripts/styles do not appear in source code (e.g. script with alert(1); only appears once).

Actual result

Scripts/styles don't work and warnings are generated:

Warning: md5() expects parameter 1 to be string, array given in libraries\src\Document\Document.php on line 676
Warning: stristr() expects parameter 1 to be string, array given in libraries\src\Document\HtmlDocument.php on line 338
