inner word selection in visual block mode `^viw` doesn't select inner word

Describe the bug
When entering visual-mode to do selections, inner-word selection fails to select the inner word, in fact, the cursor doesn't move at all.

Whilst ciw, viwc, diw, viwd, yiw, viwy etc are great for operating on inner-words, sometimes selecting multiple items in a visual block selection is more useful e.g.

1. when it's a complex op and it is useful to be able to see/preview the selection before you do the operation
2. selecting (sub)columns of data in a sheet

To Reproduce
Steps to reproduce the behaviour:

1. Create a text file with "Hello mother, hello father" he said, "I just came to say I love ya'"
2. Position the cursor at "f", ff
3. Enter visual-block mode, ^v
4. Attempt to select the word 'father' with inner-word, iw
5. Note that the cursor does not move

Expected behavior
The inner-word (father) should be selected.

Additionally in the following example, behaviour would ideally match vim, and the column should be selected up to the end of the inner-word chosen, so in the following case

first line
second line
third line
fourth

with the cursor at the f of first pressing ^vjjjiwd should leave the following:

line
 line
line

Additional context
Sorry for the spam with the edits on this issue

Reproduce the visual-block inner-word selection in VS Code 1.77.3 with VSCodeVim 1.25.2, following the listed steps and multiline example. Trace the extension's handling of ^v and iw, then verify that 'father' is selected and the multiline selection matches the expected output.
