After creating a list with around 20 fields; the default Edit form displays correctly, however after making a change to it to add a new field or by making the slightest change to it, the form does not stretch the full Hight of the browser window.
This is the original form without any changes.....

Here is how it looks after just adding one field to it and publishing back to SharePoint....

How can I get the form to stretch back to use the entire height of the window it is displaying in?
You might also notice the width changes... not a concern now, but it would be better if it wouldn't change by making an apparently unrelated change.
I already tried to change the Height on the Screen Size in the App Settings from Large to Custom and increased the size of the Height, but I can get it to stick to its correct/original height before saving/publishing the first edited version of the new form. BTW and also after adjusting the Width and Height all the Cards and Labels lose their corresponding size and location respectively from one another.
I look forward to any suggestion(s)... Thanks in advance!
Regards.
