Possibility for pass-through on non-standard data validation?
Similar to #1678 (closed), I am running into a problem with openpyxl losing data validation. Excel is apparently adding a Data Validation extension that is not supported by openpyxl, and there doesn't seem to be any way of preventing it from doing so. Our workflow also means that authoring is coming from Excel.
In my case, the data validation is not even on the same worksheet as the materials that I am attempting to manipulate, so I'm wondering: could openpyxl be modified to be conservative with its interaction with extensions, such that extension material can be left unparsed and passed through if the sheet it's on isn't touched?
I have attached a copy of the file in question: package_template.xlsx
