◊ This paragraph has set ‚Before text:‘=3cm and ‚First line:‘ =−2cm. To disable default tab stops a right tab stop at 17cm is set. The ‚Area‘ for the paragraph is set to light cyan. This paragraph has a border set with ‚Distance to content‘ of 1 cm on all sides.
The first-line indent is relative to the normal left edge of the content. But the markers in the ruler do not consider the padding, and therefore have a position 1cm to the left. Because the marker acts as tab stop position, the tab after the symbol has wrong target.
