fix: poll + inspect async renders when generating PDF #293

Closed mfontanini closed 3 months ago

mfontanini commented 3 months ago

After the changes to render +render blocks asynchronously, PDF generation was broken as it wasn't a) polling the renders and b) inspecting the renders to see if there were any images in it.
