When I enter edit mode the line wrapping becomes shorter compared to preview mode.
If I zoom out, the number of character per lines decreases and becomes quite narrow.
I would have thought if I zoomed out the number of characters per line would increase.
also I didn’t demonstrate it in the gif, however it is also affected by the width of the obsidian window.
i.e. if I use obsidian in full screen I have less characters per line compared to using half screen.
