Double-clicking on text annotations in Preview automatically changes the text size.
The issue started after installing the newest High Sierra 10.13 update. Whenever i edit/double click my Pdf's Text Annotations ("These are my notes"), then preview automatically changes the text size (Look picture #2). I then have to revert the changes by clicking CMD+Z which shows that a "Change of Bounds" (Picture 3) has been reverted. In addition, if i go to text properties (Picutre 4) it shows as Text Size 12 and Helvetica, but I have to change the new text to size 8 to match the original text (which was size 12).
This only occurs when I have saved the text annotations/changes and fully closed Preview. Then reopening the program and clicking on the notes made from the last time. The bug has been reproduced on my girlfriends Macbook Retina late-2013 with the same OS.
