            Bug ID: 142966
           Summary: Visibility of a text box over an image depends on the
                    text direction (left-right or right-left) of the
                    document
           Product: LibreOffice Online
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org

Bug definitely seen with 7.1.4.2, LibreOffice community. I am quite sure I
stumbled it with earlier versions too. I don't know how earlier.
For the unaware: western languages are written from left to right. Those are
LTR. In contrast, Arabic, Persian, Hebrew, and perhaps others, are RTL. Right
to left.

How to reproduced the bug?
1. File -> New -> Text Document
2. Format -> Page Style...
3. Text direction
   The choice of text direction is the heart of my question. I will start with
Left-to-right (horizontal). I do hope that the reader also has the choice of
Right-to-Left (horizontal). I am not sure if a Right-to-left choice does not
necessitate settings some Tools -> Options... .
4. Still with the Page Style settings, I set the Margins, each of Left, Right,
Top and Bottom, to 0. Now pressing OK shows a warning about margins setting are
out of print range. And it asks whether to apply these settings. I answered
yes, to continue applying these settings. 
5. Next thing is to Insert -> Image... . I inserted an image that is the size
of the page. Which is A4 for me. To get an image that is the size of a page,
one can separate the 1st page of a PDF file from the other pages of the file,
and convert it to an image. JPEG format, in my case. And the [PDF file I used
is
here](https://documentation.libreoffice.org/assets/Uploads/Documentation/en/IG4.2/PDF/IG4204-AddFormatImages.pdf).
6. Insert -> text box. Choose any size for it , as long as the whole box is not
larger than the image. Now enter some text in the box, and click with the mouse
any where outside the box.

And here is my point: if, in step 3, the text direction was Left-to-right 
(horizontal), then after the click with the mouse the text of the text 
box is visible. While with a direction of Right-to-left (horizontal), the text
disappears.

I have asked at
https://ask.libreoffice.org/en/question/314864/does-visibility-of-a-text-box-over-an-image-depends-on-the-text-direction-of-the-document/
before filing this report. There was one comment. Beside the commenter request
not to waste users time, he noted the image in the background is irrelevant.
Only the direction and margins are important.

Thank you.
