Exporting the following page to PDF using LaTeX used to work before XWiki 14.10 http://localhost:8080/xwiki/bin/view/LaTeX/?name=Vincent and is now failing.

The problem is this URL gets saved and generates the following export URL: http://localhost:8080/xwiki/bin/latexexport/LaTeX/WebHome?name=Vincent&pdf=true

Notice the &, which leads to the query string having a parameter of key amp;pdf and value pdf.

I have the feeling this regression was introduced in XWiki 14.10 during the refactoring of the export modal in XWIKI-19877
