ImPlotFlags_Crosshairs enables legend after disabling it

[peterwilson136]

In the below code, if you right click the plot and disable the Legend, adding the ImPlotFlags_Crosshairs flag re-enables the Legend icon. I am just wondering if this is a bug or is there a work-around so that I can simply right click to disable the legend and it re-enable in the same way.
