When I backspace, my text returns from a line.

Am I the only one who noticed that when I backslash, my text goes back one line behind? Is this a bug?

For example:

blablablablablablabalblablablalbalbla

balbalbalblalbal( now I backspace)

My text becomes like:

blablablablablablabalblablablalbalbla
balbalbalblalbal

Really annoying!
