Hint not folding, only the hint text is hidden

[duianto]

Describe the bug
Clicking to the left of a indented hints header, stops the hint from folding,
until the hint header is double clicked quickly.

To Reproduce
Steps to reproduce the bug:

1. Go to Fix Your First Error
   https://gdquest.github.io/learn-gdscript/#course/lesson-2-your-first-error/practice-85733.tres
2. Click on Hints, it unfolds and hint 1 and hint 2 are shown
3. Click on Hint 1, it unfolds and shows hint 1's text
4. Click on the empty indented area to the left of the Hint 1 header
5. Click on the Hint 1 header, only hint 1's text is hidden, but Hint 1 isn't folded

Screen recording explained:

• Hints is clicked, it unfolds and shows: Hint 1 and Hint 2.
• Hint 1 is clicked, it unfolds and shows Hint 1's text.
• Hint 1 is clicked again, it folds and Hint 1's text is hidden.
• Hint 1 is clicked again, it unfolds and shows Hint 1's text.
• The empty indentation area, to the left of Hint 1 is clicked,
  nothing happens visually (Two possibilities, more info below).
• Hint 1 is clicked, the triangle to the right rotates,
  and the hint 1 text is hidden, but Hint 1 doesn't fold,
  it just shows an empty area where the Hint 1 text was.
• Hint 1 is clicked, and Hint 1's text appears.
• Hint 1 is double-clicked quickly, Hint 1's text disappears,
  Hint 1 folds, Hint 1's text is shown, because Hint 1 unfolds
  and the Hint 1 text is drawn from the top down.
• Hint 1 is clicked, Hint 1's text is hidden, and Hint 1 folds.
• Hint 1 is clicked again, it unfolds and Hint 1's text appears.

Additional context

There seems to be two possibilities, if the empty area to the left of the Hint 1 header is clicked.

• Fold the hint to the right.
• Do nothing
