Layout exception of pull to refresh in f7-vue MD theme

Thanks for looking this question.

My English is poor. So I will use picture to show this issue.

Version: 5.5.0

Issue description:
In MD theme, page content is not following preloader to move. As follow:

In IOS theme, not have this iusse.

After I view DOM code of generating, I find transform style is added to error location. As follow:

MD theme DOM:

<div class="page-content ptr-content ptr-pull-up">
  <div class="ptr-preloader" style="transform: translate3d(0px, 132.553px, 0px);">

IOS theme DOM:

<div class="page-content ptr-content ptr-pull-up" style="transform: translate3d(0px, 140.052px, 0px);">
        <div class="ptr-preloader">

In IOS theme , the transform style is added to after page-content. But in MD theme, it is added to after ptr-preloader .

I don’t konw that is bug or not , or design is so.

Page will move to bottom ONLY in iOS theme, it is by design
