            Description

            A user reported via the forms an issue with glyph spacing using the open source version. I took a closer look and it appears there is an issue with a cache we use to store the glyph advance. The cache should be cleared when the font size is change but this isn't happening correctly and as a result the advance is being saved across a font's size change.

            In the file in question the 12pt is rendered first followed by the 13pt and thus rendered using the incorrect advance
