In a few cases, in the leak period, there can be new issues at project or file level but no new code. For example, a new analysis of the project reported new issues before of cross project duplication.
In those cases, treemap on "new code" metrics such as Technical Debt Ratio on New Code or Reliability Rating on New Code doesn't show up. The page is blank without any other explanation.
We should explain that there's nothing to display because there's no new code.
