Duplicate area symbol after editing fill pattern rotation, copy, paste

[dl3sdo]

Steps to reproduce

1. open forest sample.omap
2. edit the 409 symbol and make the fill rotation 'adjustable per object'
3. select one of the existing 409 objects and clone it via copy and paste
4. rotate the pattern in both the objects, the original and the cloned one
5. create a new pattern object and rotate its pattern as well
6. edit the 409 symbol and uncheck 'adjustable per object'

Actual behaviour

The pattern rotation for the original object is reset to north as well as for the newly created one, while the pattern rotation for the cloned object stays the same.
For the pasted object, a new symbol is created and used on paste.

Configuration

Mapper Version: master v20201227.4, v0.9.4

Thanks, Matthias, for the report. I've tried the procedure on my Linux test system and all area objects (cloned/duplicated and new ones) changed the pattern orientation to north after the last step. I'll try on Windows next.

Hm, duplicating the object by Copy-and-Paste created a new symbol. That's why changing the property of the original symbol doesn't make a difference...

... and it doesn't happen for "Duplicate" tool. @dlsdo I found bugs in the bug report 😄

[dl3sdo]

Actually I didn't use the Duplicate tool, as I was not aware of it. I used copy and paste, and only there it is reproducible.
I should have mentioned that 'cloning' didn't involve using the Duplicate tool.

The Duplicate tool is cheap (no clipboard involved).
Copy-and-Paste means saving (exporting) the selected features into XML format, putting the result into the clipboard, and importing from clipboard again - with all difficulties related to import, such as identifying identical symbols and colors. Now the question is why the symbol is different now. The last release modified two related properties: fill pattern rotation and object tags.

[dl3sdo]

If you copy and paste an object where the pattern can be rotated and disable this symbol property afterwards, the pattern can still be rotated for exactly this 'copy&paste' symbol.

1.) open forest sample.omap
2.) edit the 409 symbol and make the fill rotation 'adjustable per object'
3.) select one of the existing 409 objects and clone it via copy and paste
=> a new symbol is added to the symbol set

Reproducible also in v0.9.4.

AreaSymbol::FillPattern::equal compares the name which is a transient property, set and used by the symbol editor. Editing a symbol creates a name. Copy-and-paste doesn't carry it. Now equal claims that the symbols are different...
