Quote text and attachment missing

Are there any related issues?

Possibly #2537

What operating system are you using?

macOS Sierra (10.12.4)

What version of Nylas Mail are you using?

2.0.15

Bug?

Do you have any third-party plugins installed? If so, which ones?

None

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

Gmail (no other provider available to compare)

Is the issue reproducible with a particular attachment, message, signature, etc?

An email in a thread is missing:

The quoted email contents
The PDF attachment

The thread has multiple back-and-forth quotes, and previous emails in the chain show up properly.

The same email shows up properly in Nylas N1 (v1.5.0).

I can't post the whole email, but here's a redacted version lacking headers:

And a simpler case with more details that happens to trigger the missing attachment case:
