Ignoring "Whole group" for MapCSS Validator test "street name contains ss" is not persistent.

[mdk]

What steps will reproduce the problem?

1. Download an area in Switzerland with a street name containing "Strasse" (common writing in CH).
2. Run Validator
3. Select "Other" - "street name contains ss" group
4. "Ignore" - "Whole group"
5. Restart JOSM
6. Download same area (see 1.)
7. Run Validator again

What is the expected result?

No "street name contains ss" results.

What happens instead?

The same "street name contains ss" results as from the first validator run.

Please provide any additional information below. Attach a screenshot if possible.

You can repeat the "Ignore" - "Whole group" several times.
If you look into "ignorederrors" file, you find for each ignore operation a line like:

3000_*[name'REGEX'(?i).*Strasse.*]::org.openstreetmap.josm.gui.mappaint.mapcss.Subpart$StringSubpart@1717f5a
3000_*[name'REGEX'(?i).*Strasse.*]::org.openstreetmap.josm.gui.mappaint.mapcss.Subpart$StringSubpart@c0d5a7
...

But I think the rule identifier should be constant ;-)

In Switzerland the "ß" character is not "known" and all street names use officially "ss" instead. Instead we would need a local validator test for "street name contains ß", but local validator rules are covered by another ticket as far as I remember, but I didn't found it yet.
