Bug in the HTML field popovers

[xmijo]

Prerequisites

• Did you read the README?
• Are you running the latest version?
• Did you search other issues to see if this problem was already reported?

Description

Closing the HTML field popovers, by clicking the X, will instead exit the whole record, without saving. This is reproducible.

(Clicking outside the popover box will result in the expected behavior of only the popover closing).

Environment

Tested on latest version Chrome for macOS. I don't think the debug logs are relevant to this issue but can be added if needed. I imagine the bug is due to a faulty js link (in summernote?) and probably easily fixed considering the expected behavior is produced when clicking outside of the popover.

Steps to Reproduce

1. Create a new record.
2. Add a new field: HTML.
3. Spend an hour typing in code ;)
4. Click the corresponding button in the field toolbar to add a Link, Image, or Video.
5. Close the popover by clicking on the X in the top-right corner of the popover.
6. !!!

Expected behavior:

The popover closes, editing can continue.

Actual behavior:

The whole record closes, without saving.
