Sketch 3.5.1 Extra Break Bug

If I have 3 lines of text in a paragaph and run the plugin in Sketch 3.5.1, the plugin seems to add an additional line break between each line of text. I have to manually click into the line-height field in Sketch and TAB for it to adjust back to normal for some reason.

Reproduce the issue in Sketch 3.5.1 using a paragraph with three lines, then run the plugin and compare its line spacing with the result after focusing and tabbing from Sketch's line-height field. The issue names no source file or test, so first locate the plugin entry point; done means running it no longer inserts extra line breaks or requires manual adjustment.
