Spacing Changes In Layouts Templates

(Note 11/25): The below content is informational only. The problem in question is not demonstrated, because of the workaround currently in place.

A new post starts out with wide vertical spacing. Look at what we have here, from line to line. Nice and wide vertical spacing. Clean and easy to read. The perfect look for a blog, right?
Now, let's throw in a quote.

And now, look at the vertical spacing. With enough lines in here, you can see a change in post layout. The vertical spacing becomes much tighter. This looks sloppy. I've also seen this happen when you include <ol> and <ul> post elements. It appears to happen with any indentation element.

But let's try a test, per advice outlined below.

Look at my other posts, for instance. Enough! I Want To Go Back! and Beta Blogs: My 3 Week Evaluation both exhibit this behaviour.

Other folks who have observed this.

(Edit 11/24):See Spacing Changes In Layouts Templates #3 for an update, and now you cannot (hopefully) even see the problem.

(Edit 10/17): From Problem with the line space of the posts., we find possible hope:
As a temporary fix for current posts, I (accidentally) found that if
you add <span style="line-height: 1.4;"> before each blockquote, and </span> after the blockquote, then the line spacing goes back to normal after the quote, as it is supposed to.

So I will test this in Spacing Changes In Layouts Templates #2, and we will see how it works out.
