On my search to solve the inserting problem of tables and paragraphs I change this code.
If the document.paragraphLookup is always correct or filled no problem.
But why depend on document.paragraphLookup if it can be done direct?
So this is not a bug.
For me it is not clear why we have the dictionary paragraphLookup.
Is there a real need for the dictionary paragraphLookup, or is it just a result of historical starting ideas and should it be cleaned?

The paragraph startindex and endindex are corrupted in Document.paragraphs[].
The result was a wrong insertion of paragraphs and tables. (at wrong locations)
The function GetParagraphs had the bug. the variable index in that function should be updated after creation of the paragraph not before

The function public virtual List<int> FindAll(string str, RegexOptions options) was only resulting one item in the list. instead of a list of find idexes 
If there was only find one no big problem but if it finds more the return index was wrong also .
I think  it is a  typo error, instead of  indexes[0]  it should be indexes[i].

next newid extended on CreatePicture in Paragraph class
SetWidthsPercentage pwidth calculation extended  with * (96 / 72)  to get pixels from points

Added unit test Test_Table_SetTableDesignNone() draft. Requires fix in Tables.

Able to add columns to tables where each row have different amount of
cells

Allowing InsertColumn method take into account merged cells for multiple
row add columns where the count of cells is less than the index but is
not less table column count

On mono, the OriginalString of a Uri sometimes is prefixed with file:// leading to issues when combining paths. We strip the prefix if necesary to avoid that.

fixed lastChar initialization

fixed lastChar assignment
