wx.propgrid Update property label

There is a grid of properties
self.pg = wxpg.PropertyGrid(self, size=(500, 600), style=wxpg.PG_SPLITTER_AUTO_CENTER|wxpg.PG_TOOLBAR)

``

There is a category property on this grid.

new_signal = wxpg.PropertyCategory(name)

``

Here there are properties - descendants (it does not play a role here).

It looks like it is shown in the 1st image.

I can change the property label. After changing the rectangular size of the label does not change its size (see 2nd image).

Can I somehow fix this defect?
