I created a document with mirror margins for book layout and also mirror indents to place a note box along text in each page. Options are as follows:
Word Options > Advanced > Document view = Left to Right
Page Setup > Margins > Multiple pages = Mirror margins
Margins > Inside = 4 cm
Margins > Outside = 2 cm
Margins > Gutter = 0 cm
Page Setup > Paper = A4
Page Setup > Layout > Section > Section Direction = Left to right (Whole document)
Page Setup > Layout > Headers and footers > Different odd and even = checked
Now on even pages handles of ruler are displayed on wrong position as you can see in the second screenshot.
On Odd pages ruler handles are on correct position:
On even pages it's not correct:
This makes limitations to have a right to left paragraph among this left to right text.
Also for adding tab stops near outside margin I should go through Tabs dialogue and ruler is not functional to do it.
Is this a bug or I'm wrong somewhere?
You can download my sample document from here.
I tried this on Word 2013 and 2016, it behaves the same on both.
UPDATE
For now as a workaround I removed mirror indents and increased the amount of outside margin.
