Previously I used `CTX_copy` to create a mutable copy of the context in order to set its area and region fields to temporary variables. This was a tradeoff to avoid casting away `const` for `bContext`. However, `bpy.context` is set to this new temporary value, which is fine for a single `wm_draw_update` pass, but in the next main loop, `bpy.context` is still set to this value, which was freed at the end of `property_search_all_tabs`. It would be possible to reset the `bpy.context` variable ath the end of the function, but this patch contains an alternate solution: just don't copy the context. It looks like this was the only use of `CTX_copy` anyway, maybe for good reason. Differential Revision: https://developer.blender.org/D9216
