Exported PNG that should have a large white "W" on top-left and a transparent background

I had created a document with "none" background color and white text.
When exporting it as PNG, the PNG seems to have an alpha channel, but the background is not transparent, but white. In addition I could not find the text in the PNG file (attached).
Possibly the PNG file is invalid.

Only affects Writer, when its canvas is set transparent and exported, bg is set white. Draw will keep a transparent bg.
