$22 - 55 hand long bubble about to burst. . . or is it???

[LesJ]

Every time a small stack moved in, they doubled up, enabling this bubble to seemingly last forever. The other players left were chatty and everyone seemed to be having a good time at the table. Should I have turned chat off before making my play on this hand?
