Query regarding when parsedSize and gzipSize are calculated and shown

[Pirororor]

When inspecting the json of the report file, I see that there are quite a few components that have the following

1. assetSize, gzipSize non-zero, but "inaccurateSizes" is "true"
2. "parsedSize: 0" or "gzipSize: 0"
   
3. only assetSize field exists

Can I check under what circumstances each scenario is shown? From what I know, (1) is shown for concatenated modules, but I am not sure for (2) and (3)

Good question! I don't unfortunately have an answer off the top of my head right now.

Is there some commonality between the groups that have the sizes as 0?

I haven't dug too deep to the JSON representation of the UI graph myself so can't really help that much in there. You might need to figure this out a bit on your own. Feel free to post any insights or suggestions for the cause you could come up with, maybe someone will be able to help you ☺️
