Unnecessary comma displayed after PDF file name

[oanalavinia]

Steps to reproduce

1. Go to a page, add a pdfviewer macro with a file (e.g. pdf test.pdf file) and save the page
2. Edit the added macro for specifying a second file

At this step, the macro will display a comma after the pdf test.pdf file

And if I try to add a second file and refresh the page, more commas will be displayed

This will also lead to an unnecessary space being displayed in view mode

An workaround is to edit the source code to remove what is not necessary
