Text: Value 0 not displayed

[bartbutenaers]

Description

When a numeric value 0 is injected into the ui-text widget, it will not be shown.

The problem is that all input values are being sanetized (to avoid XSS attacks), however that should only be done for html content. Because it seems that e.g. DOMPurify.sanitize(0) results in an empty string "".

Example flow:
