With the Kit Kat update, it looks like group messaging finally works with the stock app now. I enjoyed the LG stock popup messaging and other features, so I never moved to Textra or another group app. Now, everything works!
I noticed it too and like the popup and tried to stick with it... but textra seems to send out texts/runs faster and guess prefer the ui in adding images... so i went back to textra.
