Rendering performance decreased

[schlundus]

After updating f7 to v9.0.X there is huge performance decrease (tested in chrome) during rendering

=> In v9.0.X there was a new selector introduced for autocomplete

.autocomplete-preloader-wrap:not(:has(.autocomplete-pryeloader-visible)) *

This selector seems to be a Render-Performance-Killer ... (nearly 10x slower) attached two screenshots of a very small examples,,, have a look at the invalidation count.... These lead to a heavy amount of recalculations...

I've tested the performance with the same code and F7 v8.3.X and its fast as usual ... when i remove the selector also the app is fast....

Any hints how to disable this selector?
