I asked a question on StackOverflow and later added some more information. I included a quote initially in a code block, but then I edited the question, highlighted those two lines, and clicked the "block quote" button on the top, thus adding
> to the beginning of each line. While in edit mode, the preview showed it formatted as a quote. But after saving, the page is showing it still formatted as code. You can tell because the two words
or are navy blue.
To test, I copied the URL from one browser to another browser. I can still see the two blue words, indicating it's formatted as code instead of a quote.
