[1352] Custom glyph order is not respected for space glyph

I have a custom glyph order (.notdef A Aacute …) which is displayed correctly in Glyphs, but in the exported font the space glyph is sorted at the beginning (.notdef space A Acute …) though it is somewhere further down the list. Is this behaviour intentional?

It seems to have changed at some Glyphs version, as I’m trying to export fonts matching an older version of the same font.
