Map (.tmx) -> Export as JSON is missing

Ever since updating to Tiled 1.9.2, I’ve been having troubles exporting maps to JSON. I’ve been able to do it before. I have a .tmx file and can save it. But when I export, in the combobox, all I get:

I can only save it as .tmx or .xml.

You need to use ‘Export As’ instead of ‘Save as’

This still seems like a bug. The JSON/TMJ format is intended to be one of Tiled’s native formats.
