footcitetext does not pick up footcite delims

[moewew]

See https://golatex.de/viewtopic.php?p=111333#p111333

\footcitetext does not pick up the inner cite delims from \footcite despite there being a mapping to do so.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=ext-authoryear, backend=biber]{biblatex}

\DeclareInnerCiteDelims{footcite}{\bibopenparen}{\bibcloseparen}

\addbibresource{biblatex-examples.bib}

\begin{document}
Lorem\footcite{sigfridsson}
dolor\footnotemark\footcitetext{sigfridsson}
\end{document}

It might have been nicer, easier and more consistent to just alias the delim context footcitetext to footcite, but we've gone down the other way of aliasing the outcomes later. In any case,

and

are the wrong way round and we need stuff like

\DeclareFieldFormat{extblx@innerfootcitetextdelims}{%
  \csuse{mkinner\blx@delimcontext delims}{#1}}

Maybe those field formats should be generated automatically? That would avoid a lot of repetition and hassle.

edit Corrected embarrassing typo in example. There is no "s" in \bibopenparen and \bibcloseparen.

Since the actual definition of the field formats unfortunately depends on the implementation in the styles, we can't generate them automatically. So we have to resort to field aliases here.
