RichTextLabel: changes to 'text' have no effect to text entered with append_text()

[andrea-calligaris]

Tested versions

Godot Engine v4.2.2.stable.official

System information

Xubuntu 22.04.4 LTS

Issue description

Changes to RichTextLabel's text property have no effect to text previously entered with append_text()

Due to the particular way that RichTextLabel works, with the stack and everything, it's important to highlight that this behavior is NOT consistent with the documentation, see:

Description
Any edits made to text will erase previous edits made from other manual sources such as append_text()

Workaround

The workaround is to use clear(), despite the documentation explicitly says that just setting text should be enough:

void clear()
Clears the tag stack.
Note: This method will not modify text, but setting text to an empty string also clears the stack.

Steps to reproduce

Example project provided.
Alternatively:

Steps

• Change the RichTextLabel with append_text()
• Later, through a button, attempt to clear the label with $RichTextLabel.text = ""
• Add some more text with append_text()
• The new text is going to be appended to the previously added text that was supposed to have been cleared.

Sounds like a duplicate of:

• 4.3: RichTextLabel.text = "" no longer clears contents and RichTextLabel.clear() no longer has an effect outside of scene tree #89091

Which has already been fixed but wasn't cherry picked for 4.2

[andrea-calligaris]

Yes, thanks, it's the same issue but the bug is still present in 4.2.2.

This error being present in 4.2.2 but not latest means this is resolved, sorry that I didn't notice you reopened this

Please wait for a future 4.2.x version and that issue to be cherry picked, as it has been resolved
