Please prompt:

[[getImageList?
                &tvname        = `mx_images`
                &tpl           = `@CODE:<div style="position: relative;"><img src="./assets/images/[[+property.docid]]/[[+image]]" alt="[[+property.pagetitle]]" data-hash="dh[[+idx]]"><div class="img-descr">[[+title]]</div></div>`
                &pagetitle     = `Вопрос`
                &toPlaceholder = `plbig`
                &totalVar      = `total1`
                &docid         = `2`
                &processTVs    = `0`
              ]]
 
                      <div>[[!+plbig]]</div>

The content of getImageList is read into the placeholder.
But the trouble is, when the page is loaded for the first time, it is displayed normally, after pressing F5 the placeholder is empty.

If the placeholder is not cached, then the snippet should also be called not cached:
[[!getImageList? ....
