This is not a bug, but a suggestion for a better UX.
In the function forceNoscriptElements(doc) of main_background.js, the query selector should be noscript:not([data-librejs-display]) instead of noscript:not([data-librejs-nodisplay]).
First, there is no documentation available to inform web developer of the existence of data-librejs-nodisplay. (I had to read the file main_background.js to find it.)
Second, this is bad programming to alter what was programmed by the web developer. If the _javascript_ version is acceptable, there are no reasons to prefer the non-script version, quite the opposite. The non-script version is not necessarily equivalent to the _javascript_ version (otherwise why create a _javascript_ version?).
µBlock does force noscript refresh, but only when the _javascript_ is disabled (which is logic).
NoScript does force noscript refresh all the time, which is wrong.
If you do force a noscript refresh, it should be done only if you reject some of the _javascript_ and if the web developer allowed it (data-librejs-display). Otherwise, you can assume the web developer prefer showing the web page with the partially loaded _javascript_. Of course, if all _javascript_ is disabled, you might want to redirect to the non-script version (like µBlock does).
In any case, when all _javascript_ is good, never redirect to the non-script version.
