You are the man! Thanks, appreciate your help.@TeflonDon :
If you are don't want it to be restricted at all (no click to expand or scroll feature) you can set the style property Maximum Quote Block Height (@bbCodeQuoteMaxHeight) to 0, it'll revert it to 1.1 functionality.
Either use the ACP search for @bbCodeQuoteMaxHeight or ACP -> Appearance -> Style Properties -> BB Code Elements -> Settings.
Getting the old 1.2 functionality (scroll) will be a little more intensive of a process.
