This PR doesn't seem to fix the issue-tracker-wroom/issues/108 issue. I've included a screenshot there.

Please note that I've pushed f73156f because the code was not compiling (Error: Cannot find module 'is-obj') and not linting.

Okay this PR is linked to a few issues.
https://github.com/prismicio/issue-tracker-wroom/issues/108
and
https://github.com/prismicio/issue-tracker-wroom/issues/380

The issue is fixed :) I also added a test

[francois-riviere]

but Baptiste was saying that the PR doesn't fix #108

[MarcMcIntosh]

@francois-riviere did he say that today?

I made a small change then added a test, you can see the results in the picture in this comment https://github.com/prismicio/issue-tracker-wroom/issues/108#issuecomment-874822253

[francois-riviere]

he left a comment just above on Mar 12

Hello,

Sorry to comment on an old PR. Do we know if this has been resolved in newer versions of Prismic?
