My standard page layout has a Visualforce page embedded. When this embedded page is rendered in Classic it shows properly but when in Lightning Experience, it appears to be forced to a shorter height, no buttons at the bottom are showing and also there is no scrollbar. I am using 'lightningStyleSheets' attribute. In the embedded page settings, show scrollbars is not checked, and I think that might be the reason why I do not see scrollbars? I do not see the entire content of the embedded page , and there are no scroll bars to scroll to see it. Any suggestions or ideas are welcome. Below are screenshots for classic and lightning. Any ideas?
