TWebBitBtn question about glyphs

In the IDE, I can set MaterialGlyph and the glyph shows up as a glyph on the form.

But at run-time, it shows the name of the glyph that's in the MaterialGlyph property.

What does it take to get the glyph to show up at run-time in the browser?

You need to add the material icons lib reference (project context menu, Manage JavaScript Libraries)
