[PropertyView] Multi-line value with dtype text can easily be overwritten

[mpsonntag]

When a Property.value with the dtype 'text' and a multi-line content is displayed, it only shows the first couple of characters and '[...]' to indicate, that the value contains more text. When this value is switched into the editable state, it still only displays the abreviated value. When the editable state is exited, this will be seen as a change event from "long text, multiline text" to 'abbreviation [...]' without any feedback to the user.

In this case a safety question should be asked if the value content is supposed to be overwritten.
