\textcite macro produces "Author (year)" correctly but colours first paren with hyperref

Question

I am using a custom \textcite macro that I found somewhere. It works nicely except that it makes the opening paren of "Author (year)" part of the link (also colouring it blue) which is not desired.

This is likely just a minor change to the definition of the macro, but the solution eludes me (I don't get where the opening paren is added at all).

Opening paranthesis should not be part of link and should not be coloured.

(M)WE:

            natbib=true,
            minnames=1,     %% prevent truncation to year-only
            backref=true, %% TODO REMOVE before final
            bibstyle=apa,

Answer 1

After the discussion in the comments I will answer this question for style=authoryear, (or more precisely, citestyle=authoryear,). If you are interested in a solution for APA style (of course again only citestyle=apa, matters), see BibLaTeX Colors And Links Only The Year Not The Rest Of The Citation.

The principle to get fuller linking is the same as in BibLaTeX Colors And Links Only The Year Not The Rest Of The Citation just adjusted to the (simpler) citation style authoryear.

Again, there are many alternatives to get a greater link area (hyperlink name with biblatex authoryear (biblatex 1.4b), hyperlink name with biblatex authoryear, Biblatex, authoryear-comp, and hyperlinks, Inconsistent bracket color with citet and citep), but I feel this one is the safest (if definitely not the shortest)
