Short description of error
after changing location or rotation and calling for bpy.context.scene.update(), the world_matrix does not change.
It seems to stay stale as long as the popup is active.
On popup reactivation, the matrix gets updated once(sometimes twice) and then goes stale again.

Exact steps for others to reproduce the error

paste code below to 'scripting' and run it
launch operator from 'space'(search) popup: 'TEZZT_P'
change float property
notice, how the object is moving, but the printed in the console(as 'INFO' message) values do not change
release operator popup
launch again
notice that the printed 'INFO' values have changed, but do not via slider any more

import bpy

class OpTeztPopup(bpy.types.Operator):
    bl_idname = "tezt.op_tezt_p"
    bl_label = "TEZZT_P"
    bl_options = {'REGISTER', 'UNDO'}

    location_x : bpy.props.FloatProperty()

    def execute(self, context):
        d1 = str(context.object.matrix_world[0][3])
        context.object.location[0] = self.location_x
        
        #throw everything, something might stick:
        context.scene.update()
        bpy.context.scene.update()
        
        d2 = str(context.object.matrix_world[0][3])
        debug = "{} ::: {}".format(d1, d2)
        print(debug)
        op : bpy.types.Operator = self
        op.report({'INFO'}, debug)
        return {"FINISHED"}

    def invoke(self, context, event):
        return context.window_manager.invoke_props_popup(self, event)
