Description:
LibreOffice Calc with jpg pictures pasted into xlsx worksheet. Save. Delete a graphic. Undo will not recover the deleted graphic. Also Undo is not an available command after deleting a text box. The text box or graphic is gone and unrecoverable. Seems to involve XLSX format, problem does not involve ODS format. Seems that LO does not notice that there is a change in document. Completely resetting all parts of user profile does not fix. I don't know what version this started with.

Steps to Reproduce:
1.Open a Calc spreadsheet, save as .XLSX (not .ODS)
2.Do Either or both:
 2A. paste a JPG picture, or
 2B. Pull Insert menu to Text Box. Drag a box & type some text in the box. 
3 Save
4.Delete the picture or text box
5.Try to Undo the deletion. Not possible. 
6.Close document- LO will not ask if you want to save because it did not notice the change. 
NOTE: This does NOT happen in safe mode, but it does always happen for XLSX spreadsheets in regular mode even with a newly reset unmodified user profile. 

Actual Results:
Picture or text box is deleted, and Undo command does not undo the deletion of it. Data is lost. Document does not notice it has been edited since last save. Status bar does not show red disk. Problem happens with XLSX document type, but not ODS.

Expected Results:
Expected that Undo would reverse the last delete command and restore the deleted item. Expected that status bar will show red disk to indicate unsaved changes. 


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
