drop_callback not working for 2nd and more axis since version 2.0.0 (working with 1.10.1)

[GermainHebertABB]

Version of Dear PyGui

Version: 2.0.0
Operating System: Windows 11

My Issue/Question

When using multiple axis on a plot. The drop_callback is not working for 2nd and more axis since version 2.0.0 (working with 1.10.1)

To Reproduce

Simply put two axis with callback, drag an item into it. The 2nd axis isn't going yellow and no callback are call.

Expected behavior

Same script was working well with drop back with 1.10.1

Standalone, minimal, complete and verifiable example

        def new_axis_drop_callback(y: str):
            def _callback(_s, app_data, _u):
                dpg.add_text('new axis', indent=10, parent="Console")
                ds: DataTable = app_data["dragged_data"]
                if dpg.does_item_exist(ds.formatted_key):
                    return

                if ds in {TimeseriesDataTables.FRINGE_EDGES}:
                    add_stem_series(ds, y)
                else:
                    add_line_series(ds, y)

            return _callback

        with dpg.plot(
            drop_callback=plot_drop, payload_type="plotting", width=-1, height=-1, tag="log view",
        ):
            dpg.add_plot_legend(payload_type="plotting")
            dpg.add_plot_axis(dpg.mvXAxis, tag="x_axis", label="t")
            dpg.add_plot_axis(
                dpg.mvYAxis,
                tag="y1_axis",
                label="y1",
                drop_callback=new_axis_drop_callback("y1_axis"),
                payload_type="plotting",
            )
            dpg.add_plot_axis(
                dpg.mvYAxis,
                tag="y2_axis",
                label="y2",
                drop_callback=new_axis_drop_callback("y2_axis"),
                payload_type="plotting",
            )
            dpg.add_plot_axis(
                dpg.mvYAxis,
                tag="y3_axis",
                label="y3",
                drop_callback=new_axis_drop_callback("y3_axis"),
                payload_type="plotting",
            )

You need to change these 3 to another string:
"y1_axis", "y2_axis", "y3_axis"

because the terminal says: Message: Alias already exists.
If drop_callback still not working, can you provide a short/reproducible example?

[nvglucifer]

My bad about those string, I might forget to rename it - duplicate.

yes, The 2nd axis isn't going yellow and no callback are call.
because of some related issue (#2409, #2459, #2387, #2502).

I see it worked by modifying mvPlotting.cpp line#513 - #2502.
