Clarification;
This is related to Shape/Text widget switching.

This occurs when switching widgets between shape and text.

• When Pasting (a numbered list) into a shape, then later switching to text widget
• Switching from Text to Shape, then back from Shape to Text.

This occurs when formatting text in a Text widget when source text contains numbers.

• When a numbered list of text, is in a text widget, and only part of the list is selected and converted to numbered list.
  e.g. A list of 5 items, and formatting 4/5 items to a numbered list.
  e.g. A list of 5 items and de-formating 2/5 items to remove numbered list
  e.g. A list of 5 items and choosing bullet-point format.

This does not occur using unmodified text with Text widgets.

• Pasting a numbered list into a text widget.
  (Source text remains unchanged, Miro suppresses the repeated numbers)
• Typing into a text widget.
  (Miro formats correctly, but doesn’t change the source text)
