We configured non-empty description for freezing which works fine for a project where no description was set. After adding a description, saving, deleting the description, saving again however also projects with empty descriptions can be frozen without an error. The reason is that the description is not really empty but rather contains "<p><br></p>"

Proposed solution: workbench 2 should recognize situations where the text is (effectively) empty (only consists of tags, whitespace, &nbsp and no content) and turn it into an empty string.
