Checklist

• I've looked at the documentation to make sure the behavior isn't documented and expected.
• I'm sure this is an issue with Summernote, not with my app or other dependencies (Angular, Cordova, React, etc.).
• I've searched through the current issues to make sure this hasn't been reported yet.
• My issue is pertinent to this repository of Summernote (jQuery), or I was unable to have my issue resolved from the relevant version I'm using, such as Angular, dJango, Rails or React. Please try your issue at the relevent repository first.
• I understand that issues without interaction for more than 14 days (2 weeks), may be closed at our discretion. We do this, as sometimes issues are abandoned. We may at our discretion, add issues to the relevant project to be looked at, or for maintainers to work through as time permits. This is to help keep issues relevant to the current version of Summernote, and to reduce clutter.
• I agree to follow the Code of Conduct that this project adheres to.

Found previous related issue: #368 from 2014

This line looks to be the culprit:

summernote/src/js/editing/Style.js

Line 149 in 542738a

styleInfo['line-height'] = para.style.lineHeight;

Changing it to: styleInfo['line-height'] = parseFloat(para.style.lineHeight).toFixed(1); seems to fix the issue

The line height has a decimal point In the toolbar. The list shows whole numbers without decimal parts.
The checkmark gets added when both values are the same.

There are three options to solve the issue:

1. Present whole numbers without decimal parts in the toolbar.
2. Present whole numbers with decimal parts in the list.
3. Make the comparison tolerant for the presentation.

If you would like to make the source changes and submit a PR, I'd be more than happy to test and merge the changes. However, please keep in mind, that I am currently working in the middle of Potato Harvesting season, and am working 10 hour days most days as I'm needed. I'm not sure when I'll be available more often, so any PR's may take a little longer to test and merge.
