Fieldset Collapsed="true" breaks layout

I'm using the Fieldset components in a Blazor application. When the Collapsed property is not defined (defaulting to "false") the layouts of the contents inside the Fieldsets are correct. However, if I set the Fieldsets to start in the collapsed state (Collapsed="true"), when the Fieldsets are expanded, the layouts are broken. The ChildContents inside the Fieldsets are various divs with flex or grid contents.
Thank you.
