getLimits() doesn't change when I set the paper size

[gswifort]

Should changing the paper size cause the Db.Layout.getLimits() value to change? It doesn't change for me.

If I change the paper size in the UI, .getLimits() adjusts the values ​​to the current paper size, but if I set the paper size from PyRx, these values ​​don't change, even if I save the drawing and reopen it.

from pyrx import Db, command


@command
def demo3():
    db = Db.curDb()
    layout_id = db.currentLayoutId()
    print_plot_cfg(layout_id)
    # layout.getPlotCfgName()='DWG to PDF.pc5'
    # layout.getCanonicalMediaName()='ISO_full_bleed_A4_(210.00_x_297.00_MM)'
    # layout.getLimits()=(PyGe.Point2d(-0.00000000000000,-0.00000000000000), PyGe.Point2d(21.00000000000000,29.70000000000000))
    set_plot_cfg(layout_id)
    print_plot_cfg(layout_id)
    # layout.getPlotCfgName()='DWG to PDF.pc5'
    # layout.getCanonicalMediaName()='ISO_full_bleed_A0_(841.00_x_1189.00_MM)'
    # layout.getLimits()=(PyGe.Point2d(-0.00000000000000,-0.00000000000000), PyGe.Point2d(21.00000000000000,29.70000000000000))
    
def set_plot_cfg(layout_id: Db.ObjectId):
    layout = Db.Layout(layout_id, Db.OpenMode.kForWrite)
    pcv = Db.PlotSettingsValidator()
    pcv.setCanonicalMediaName(layout, "ISO_full_bleed_A0_(841.00_x_1189.00_MM)")

def print_plot_cfg(layout_id: Db.ObjectId):
    layout = Db.Layout(layout_id, Db.OpenMode.kForRead)
    print(f"{layout.getPlotCfgName()=}")
    print(f"{layout.getCanonicalMediaName()=}")
    print(f"{layout.getLimits()=}")
