When editing tags in the relation editor <TAB> will highlight new fields but not place the cursor there, this inhibits copy/paste

[avar]

When creating a new relation and adding new tags pressing "<TAB>" inside the tagging dialog will advance to the next tag but it won't make the cursor active in that field.

This has the downside that if I Ctrl+V or middle click (on Unix) text won't be pasted in the field. I have to click on it with the mouse and then paste.

It would improve the UI if the cursor was automatically made active in the field. When it's active <TAB> still advances to the next field so I can't see a downside with that.
