How to scroll up the page until the material dialog closes or close the dialog before switching to another route?

Question

Angular

I have implemented scrolling the page up when switching from one route to another, everything works fine until I go to the route via the link located in the material dialog.
It turned out that the material dialog sets the class "cdk-global-scrollblock" to the html tag, which in turn sets the styles position: fixed; width: 100% in which the elementary window.scroll does not work ... at all ...
But the funny thing is that this state remains for quite a long time after the dialog is closed, so long that from time to time we have time to switch to another route and naturally stay in the same place.
I tried to remove the "cdk-global-scrollblock" class through beforeClosed and scroll in it, and I saw this picture
I scroll the page down, open the dialog, close it, the page scrolls up and immediately goes down again.
I just need to disable this behavior. I will be glad to advice
