Repro: Enter some text (at least one word) into the first line of an empty writer-document. Press the toolbar-button for decrement indentation. After 4 clicks the text disappeared on the left border of the document. There is a similar (closed) issue coming from OOo: (https://issues.apache.org/ooo/show_bug.cgi?id=69537). This behaviour is reproducable on all OOo/LibO-versions I had (OOo3.2, 3.3, LibO3.3, 3.4, 3.5) Btw.: If you increase the indentation instead it stops on the right border of the paragraph area.
Exepectation: Negativ indentation stops, if the first character of paragraph would leave the page (not paragraph area).
Thanks for bugreport Other Word processors also allow to place something outside of page. It is not bad, even handy. Problem in another: why objects outside of page are invisible? They should be visible (more handy variant). Or should be some marks that indicates that outside of page something exist.
This seems to be consistent with other word processors. It would be good to have some indication that content is off the page, however.
Created attachment 70588 [details] Basic macro, which solves problem with "Decrease Indent" I have written Basic macro which performs decreasing indent of paragraph and watches for paragraph not appear outside of page. Paragraph stops moving on left side of page. By default it moves on 25mm to left. This value can be changed inside of macro.
