Twitterbot cannot parse card metadata from pages that are too big - about 32700 bytes max

I just spent about an hour trying to figure out why the heck the card validator was failing. It seems that twitterbot has some buffer with a max size of 32768 bytes which contains the page plus some other data, and if you give it more data than that, it fails to parse the meta tags.

This is a bug. Where can I report it?

Test cases:

If you go to https://cards-dev.twitter.com/validator and enter them in, the second one returns

INFO: Page fetched successfully
WARN: No metatags found

the only difference between the pages is a few extra characters, and it doesn’t seem to be content dependent.

If any twitter staff have looked at this, could I please get an acknowledgement?

Bump. I’m not sure what else I can do here - I provided a test case.
