Conditional formatting area extending

I put conditional formatting rules to cell that in named scope (only 1 cell in scope, it's inner horizontal scope) and instead of enlarge affected area to scope (any, not for all parent rows not for inner horizontal columns) it just copied (with overlapping).

It makes generation very slow and if you have just 3 conditions in result file you get 9 in each cells.

Start by locating the conditional-formatting handling for named scopes and reproduce the issue with a one-cell inner horizontal scope and three conditions. Check how rules are copied or expanded during report generation. Done means the intended scope is covered without overlapping duplicate rules and generation no longer multiplies conditions across cells.
