# short text: full width, no scrollbar

# ----- And now let's see the behaviour with `overflow-y: scroll`:
# short text: reduced width, scrollbar
["scroll", "auto", 1, "short_text", 78, True],
# long text: reduced width, scrollbar
["scroll", "auto", 1, "long_text", 78, True],

# long text, `scrollbar-gutter: stable`: reduced width, scrollbar
["scroll", "stable", 1, "long_text", 78, True],
# ------------------------------------------------
# ----- Finally, let's check the behaviour with `overflow-y: hidden`:
# short text: full width, no scrollbar
["hidden", "auto", 1, "short_text", 80, False],
# long text: full width, no scrollbar
["hidden", "auto", 1, "long_text", 80, False],

# long text, `scrollbar-gutter: stable`: reduced width, no scrollbar

# ----- Bonus round with a custom scrollbar size, now that we can set this:
