SupportNoScriptEnabled and Googlebot user-agent not working

[Viliam Mihálik]

Hello,

 I testing SupportNoScriptEnabled with following user-agent:  Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html, from https://support.google.com/webmasters/answer/1061943?hl=en. When you try to fetch url with filter lazyload_images for example, for Googlebot user agent noscript not work. I attached two images with Googlebot user agent and Chrome user agent. You can see that noscipt part with redirect is not included. According to documentation(https://www.modpagespeed.com/doc/faq#noscript-redirect) it should work with "defer_javascript, lazyload_images, dedup_inlined_images, and local_storage_cache". I test all filters and problem is with all filters excpet defer_javascript.  Use case is when you want to detect noscript user via noscript get parameter you need to have enabled defer_javascript filter, but this exact filter cause problem in my application so ia am unable to detect if google bot access my page without JS.
