When inserting a blockquote in an empty post and immediately pressing the blockquote button again, with no text entered, a few strange things happen.
On API 16-19, the blockquote is not removed. On an API19 emulator I was able to remove the blockquote by using backspace, but on my API18 Samsung S3 I can't remove the blockquote that way either (I have to enter text, then toggle off the blockquote, then deleted the text).
On API 21+, the blockquote is removed but leaves behind an empty space above the cursor. Ideally, the placeholder text would reappear instead.
