Description

My favourite project has been gradualy getting slower and slower to open and use. I opened the project today in VIM and see that it has thousands of repeated address blocks in the metadata:

         <address> 
            <type></type>
            <address></address>
            <city></city>
            <administrativearea></administrativearea>
            <postalcode></postalcode>
            <country></country>
          </address>

My project file now has grown to 3.9 GB:

Added by Nyall Dawson almost 8 years ago

Fix metadata address element doubles with each project write

elementsByTagName can be dangerous, because it returns children
recursively. In this case the contact "address" element contained
a child element for the street address, also named "address".

So when restoring a project with contact addresses in the metadata,
each address was created twice...

Fixes #17940
