TASKFILE_DIR resolved incorrectly in dynamic variables of included Taskfiles

Description

Setup

./
├── Taskfile.yaml
└── common/
    ├── Taskfile.yaml
    └── foo.sh

Taskfile.yaml

version: 3

includes:
  shared:
    taskfile: common

tasks:
  pwd:
    desc: Print the current working directory.
    cmds:
    - pwd

common/Taskfile.yaml

version: 3

vars:
  foo:
    sh: '{{.TASKFILE_DIR}}/foo.sh'

tasks:
  pwd:
    desc: Print the current working directory.
    cmds:
      - pwd

common/foo.sh

The content of this file doesn't really matter.

#!/bin/bash
echo "foo"

Actual Behavior

Calling task shared:pwd works as expected:

task: [shared:pwd] pwd
/var/folders/b8/g43jjlg51gs4h13yf49sjmjm0000gn/T/tmp.6yctrFQfZM/tasktest

However, calling any task from the root Taskfile sets TASKFILE_DIR to the root Taskfile's directory for variable resolution, leading to this error:

stat /var/folders/b8/g43jjlg51gs4h13yf49sjmjm0000gn/T/tmp.6yctrFQfZM/tasktest/foo.sh: no such file or directory
task: Command "/var/folders/b8/g43jjlg51gs4h13yf49sjmjm0000gn/T/tmp.6yctrFQfZM/tasktest/foo.sh" failed: exit status 127

Expected Behavior

{{.TASKFILE_DIR}} in the common/Taskfile.yaml file should always resolve to the common subdirectory, never to the directory of the including Taskfile. The current behavior makes it impossible for the included Taskfile to reference a file next to it (at least without knowing the relative path from including to included Taskfile).
