Does operatorPendingModeKeyBindings work with visual selections?

This might be me doing something dumb here but I'm trying to get operatorPendingModeKeyBindings to work with a visual selection, ie move, visually select text. This works in normal vim through various trickery like normal! but that doesn't seem to apply here and I'm not sure if I'm doing something wrong or it's a bug as it seems to do something not quite correct.

with this setup:

    "vim.visualModeKeyBindings": [
        {
          "before": ["i", "l"],
          "after": ["^", "v", "g", "_"]
        },
    ],
    "vim.operatorPendingModeKeyBindings": [
        {
          "before": ["i", "l"],
          "after": ["^", "v", "g", "_"]
        },
    ],

I am trying to delete/copy/yank an "inner line", ie. all text in the line but excluding whitespace on either end. There is no text object for this in vim so accomplishing via visual mode is a common setup. I move to beginning of the line, go into visual mode, and move to end of line (whitespace exclusive). The result is this:

Compare this to vim which deletes the entire line but leaves the whitespace:

It seems that the initial ^ is respected as part of a range but going into visual mode aborts the operation.
Am I setting this up wrong? Note that the original vim setup is this:

vmap il :<C-U>silent! normal! ^vg_<CR>
omap il :normal ^vg_<CR>

I dug through the code a bit to know that normal! isn't supported (yet) so the <CR> shouldn't be required and silent! is ignored.

Debug logs on init are (note it doesn't seem to log pending operation remaps):

Thanks for any help!

Reproduce the issue with the shown vim.visualModeKeyBindings and vim.operatorPendingModeKeyBindings settings, using the operator-pending debug trace as the starting point. Trace the remap through the ^, v, g, _ sequence and confirm that the visual selection completes the delete, copy, or yank with the intended whitespace boundaries.
