Blockwise deletion with charwise choice (i.e. dva}) misses last brace

[hardenedapple]

Problem

When spanning multiple lines, da} acts likewise.
One would use dva} to force charwise action.
This mostly works, except that the last character is not deleted.

Steps to reproduce

Editing the text below (with nvim --clean):

abcd{
  hello
  }abcd

Position cursor in between braces.
Type dva}.
Observe that file now contains abcd}abcd

Expected behavior

File should contain abcdabcd.

Neovim version (nvim -v)

NVIM v0.9.5, Also v0.10.0-dev-2574+g41fb98d6f

Vim (not Nvim) behaves the same?

Yes, 8.2 and 9.1

Operating system/version

Linux -- both Arch and Ubuntu

Terminal name/version

XTerm(390)

$TERM environment variable

xterm-256color (also happens inside tux)

Installation

original vim installed using package manager, nvim installed from source.

This is working as intended:

							*o_v*
v		When used after an operator, before the motion command: Force
		the operator to work charwise, also when the motion is
		linewise.  If the motion was linewise, it will become
		|exclusive|.
		If the motion already was charwise, toggle
		inclusive/exclusive.  This can be used to make an exclusive
		motion inclusive and an inclusive motion exclusive.

However, it seems that the toggling of inclusive/exclusive isn't working.

What is "likewise"? I tested this and it acts charwise.

Hmm ... I could have sworn I tested it and saw it act linewise, but it's clearly not doing that for me now.
No idea what I did differently then to now ...
