Remapping `Home`/`End` or `0`/`$` does not work in visual mode

Describe the bug
Remapping Home/End or 0/$ does not work in visual mode in settings.json.

To Reproduce
Steps to reproduce the behavior:

1. Add these in settings.json to "vim.visualModeKeyBindings":

            {
                "before": ["0"],
                "after": ["F"]
            },
            {
                "before": ["F"],
                "after": ["0"]
            },
            {
                "before": ["$"],
                "after": ["L"]
            },
            {
                "before": ["L"],
                "after": ["$"]
            },

2. Ensure new settings take effect either though a save or a reset.
3. Hit ESC to ensure you're in normal mode.
4. Hit 'v' to ensure you're in visual mode.

Expected behavior

• Hitting 'F' will move the visual mode highlight to the beginning of the line
• Hitting 'L' will move the visual mode highlight to the beginning of the line

Actual behavior

• Hitting 'F' will do nothing
• Hitting 'L' will move the cursor and the visual highlight to the bottom of the page
• Hitting either key will intermittently make the editor unresponsive to keyboard input

Additional context
Remapping 0 to F an $ L works correctly in normal mode. This is only an issue with visual mode.

Reproduce the issue using the settings.json entries under vim.visualModeKeyBindings, then compare the behavior in normal and visual modes. Trace the visual-mode keybinding handling and verify that remapped 0/$ or Home/End keys move the selection as expected without making keyboard input unresponsive.
