This is a different code path than the one discussed in bug #59711.

IIUC, your proposal might work to improve the performance for the use case
described in the other bug (but less so this one).
Please, repeat it there. (If the comments are spread over different reports,
it might be difficult to retrace in the future what was done [and why] for
that specific bug.)
