Content Layout blockquote rewriting a righthand quote mark

Anyone else ever seen this sort of behavior? If I have a blockquote that itself has a set of single-quote mark, and I use my Content Layout blockquote tool, then the righthand quote mark gets changed from curly quote to straight.

It will be rewritten (straightened) if I am editing either the regular text or the source code.

And if I make a blockquote using the standard tool in the editing toolbar, all is fine though.

See this example with both kinds of blockquotes (and the two ‘jack of all trades’):
