[QGIS-Developer] QgsProcessingParameterMatrix - numberRows is not respected in the UI

[René-Luc Dhont]

Hi Nyall,

Thanks for the answer.

To work around the issue, I have to provide a default value.

In the case of a QgsProcessingParameterMatrix with fixed rows number has 
a default value have to be provided by the definition or the class ?
