Accessibility issue: PDF focus tab order is not logical - form fields tab from right to left instead of left to right

[alexarobu]

Describe the bug
Hi,

It has been observed that on the PDF version of a record (exported from the record's full or default view), the form fields for the map coordinates tab from right to left, instead of left to right. This does not follow the logical order which is visually seen on screen.

It was also flagged that Adobe Acrobat warns of several issues with the tab order of the PDF as a whole.

I couldn't really figure out what is the cause of this, so I couldn't find a fix for it.

To Reproduce
Steps to reproduce the behavior:

1. View any metadata record (either in default or full view)
2. Download the record as PDF
3. Open the PDF in Acrobat Reader Pro
4. See the error for tab order in the Tab Order section of the Accessibility Checker
5. If you press the tab key until you get focused to the coordinates of the geographic extent you will notice that the order in which these are focused is from right to left instead of left to right

Expected behavior
It is expected that the tab order parallels the document structure.
