Topic on Talk:MediaWiki 1.28/Flow

a weird issue with 1.28.0

With interfacing with google maps api on an page using protected js , sometimes my div map-container appears ( strong feeling) to be delayed during page creation , and the api complains with :

Uncaught TypeError: Cannot set property 'position' of undefined

at new _.Sl (common.js:29)

at Object.Yy.f (map.js:44)

Version 1.25.5 works smooth without any issue's

Does anyone have suggestions????

note Part of local settings

function wfHtmlNamespace() {

if( array_key_exists( 'title', $_REQUEST ) ) {

$title = Title::newFromText( $_REQUEST['title'] );

if( is_object( $title ) ) {

global $wgRawHtml;

$wgRawHtml = $title->getNamespace() == NS_QBOX;

}

}
