I have popover inside mat-grid-tile and its not being opened because of overflow:hidden.To override it,I added a css class and changed the attribute as overflow:unset and that works fine.But problem is that when page is getting reloaded,this unset is being override by .mat-grid-tile css class and I don't know why this happens.I have to override it as you can see on my images.How can I do that?
A demonstration of my app on stackblitz:(Here this problem never occurs,I shared this to show you my layout design)

When page refreshed
After I changed it manually in the console(it look like this whether page refresh or not)
