Guild Wars 2

Now I took the time to make a significant search on the web and in here before posting this just to make sure that I got it right.
I have found posts over 6 months old which have been answered by ArenaNet and they were going to look into this ongoing problem. However since I just read a couple of similar posts posted no more than 3 days ago I feel it must be brought to the attention of the staff once again.
When inside a dungeon there is no “dungeon leader” according to ArenaNet, so there is no way to prevent the party dissolving when someone leaves or disconnects and another player is needed to fill the empty space, which leads me to the problem:

LFG dungeon merging parties is still very bugged indeed.

I had started a party (through the LFG tool) for a story mode Ascalonian Catacombs (AC) and after the first boss one from our party left/disconnected, after waiting for 2 minutes for the person to come back we decided to votekick so we could continue with another player. As soon as the votes were in we all got kicked out of the dungeon. So we tried one more time, this time two players disappeared and one left the party without any problems and someone else initiated a votekick and before I could warn them the player was kicked but nothing bad happened. We even got two new players and continued foward until at the third boss someone else left/disconnected and we thought why not try the votekick and get someone else since it worked so nicely before, but alas we all got booted out from the dungeon just like the first time.

I would very much like to know why it is this issue has gone for so long unnoticed or is this just a bug that apparently only rears its ugly head once every second time you try to use the LFG tool or use the votekick function while inside a dungeon?
