Gallery format: Images cannot close overlay fancybox due to: ".style.removeAttribute is not a function"

Setup

• MW version: 1.31
• MW Skin: Vector
• DB (MySQL etc.):
• PHP version: 7.2.10-Ubuntu
• SMW version: 2.5.8
• SRF version: 2.5.6
• Browsers and versions (if applicable): Chrome, lates (70.0.3538.102)

Issue

Gallery result with overlay=yes produces images that when clicked, you cannot closed it due to this JS error in fancybox code:

VM2724 jquery.fancybox-1.3.4.pack.js:31 Uncaught TypeError: j.get(...).style.removeAttribute is not a function
    at HTMLDivElement.S (VM2724 jquery.fancybox-1.3.4.pack.js:31)
    at HTMLDivElement.opt.complete (VM2647 load.php:7236)
    at fire (VM2647 load.php:3317)
    at Object.fireWith [as resolveWith] (VM2647 load.php:3447)
    at tick (VM2647 load.php:7079)
    at Function.jQuery.fx.tick (VM2647 load.php:7405)
    at schedule (VM2647 load.php:6783)

It seems similar to these fixed issues:

• nvidoni/fancybox#2 and
• igorlino/angular-fancybox-plus#2

Could it be that SRF uses an outdated outdated jquery.fancybox.1.3.4 lib (vs the more recent 3.+ line)? Or is it an interaction with other extensions/skin?

Steps to reproduce

Assuming there are files in the wiki, run this query and click on the result pages with the JS-console open to see the error:

{{#ask: 
 [[File:+]] 
 |format=gallery
 |overlay=yes
}}
