JS Bug with PHP 7.3?

[criwe]

Hi!
I´ve switched from PHP 7.2 to 7.3 in an TYPO3 9.6 with Flexslider 1.5.14. That leads die JS-Errors because of different inline js:

PHP 7.3:

jQuery(document).ready(function(){jQuery('#flexslider-59').flexslider({animation:"fade",animationLoop:!0,itemMargin:"0",easing:"swing",direction:"horizontal",reverse:!1,smoothHeight:!1,startAt:"0",slideshow:!0,slideshowSpeed:"6000",animationSpeed:"2000",initDelay:"0",randomize:!1,pauseOnAction:!0,pauseOnHover:!0,useCSS:!0,touch:!0,video:!1,controlNav:!1,directionNav:!0,prevText:"Zurück",nextText:"Weiter",keyboard:!0,multipleKeyboard:!1,mousewheel:!1,pausePlay:!1,pauseText:"Pause",playText:"Abspielen",controlsContainer:"{settings.controlsContainer}",manualControls:"{settings.manualControls}",sync:"{settings.sync}",asNavFor:"{settings.asNavFor}",itemWidth:"{settings.itemWidth}",itemMargin:"{settings.itemMargin}",minItems:"{settings.minItems}",maxItems:"{settings.maxItems}",move:"{settings.move}",carousel:{settings.carousel},start:function(slider){jQuery('body').removeClass('loading')}})});

Problem width PHP 7.3 here -> "{settings.controlsContainer}" instead of ""

PHP 7.2:

jQuery(document).ready(function(){jQuery('#flexslider-59').flexslider({animation:"fade",animationLoop:!0,itemMargin:"0",easing:"swing",direction:"horizontal",reverse:!1,smoothHeight:!1,startAt:"0",slideshow:!0,slideshowSpeed:"6000",animationSpeed:"2000",initDelay:"0",randomize:!1,pauseOnAction:!0,pauseOnHover:!0,useCSS:!0,touch:!0,video:!1,controlNav:!1,directionNav:!0,prevText:"Zurück",nextText:"Weiter",keyboard:!0,multipleKeyboard:!1,mousewheel:!1,pausePlay:!1,pauseText:"Pause",playText:"Abspielen",controlsContainer:"",manualControls:"",sync:"",asNavFor:"",itemWidth:"0",itemMargin:"0",minItems:"0",maxItems:"0",move:"0",carousel:!1,start:function(slider){jQuery('body').removeClass('loading')}})});

It´s an old, big installation, so could also have other causes (maybe configuration issue?!).
But switching back to PHP 7.2. fixed the mentioned problem.

Maybe someone can confirm that issue?

Same here - did someone find a solution other than downgrading back to PHP 7.2?
