The problem is the same for both editors, they just can't decide what is inner and outer without loading the full relation - in case of iD I don't know if this is even possible. When handling huge multi-polygons like this, JOSM is a much better choice. E.g. because you can selectively load the forests on a large area without data you're not interested in.

Let me know if you need help here,
Jan

JOSM shows the marker on the wrong side, because there is no way to decide which is the right one by looking at one outer way only. As soon as you download the whole multi-polygon, it switches to the correct side.
There is no "backwards" with respect to the direction of outer ways of multipolygons.

Hi,
why did you remove all the good tags again and re-added many tags that don't seem to belong to OSM?

Cheers, Jan

Hi,
could you check the tagging of this node? Looks like something went wrong with copy and paste.

Cheers, Jan

Hi,
the tagging of this node doesn't seem right.
It is now a sports center, a group home, a foundation and a locality in the same place.
Could you correct this?
Jan

I didn't mean adding the villages, just these tags. They don't look like they belong to OSM and are not used in other places.

Hi,
you added 45 villages with some strange tags, was this a mistake?
E.g.
CODE94X=903035
GLOBAL=0
PRIORITY=NONE
VILLAGE_ID=5826
node/4227632087

Cheers, Jan

Hallo,
hier sind 8 Wege ohne Tags entstanden, kannst du da nochmal nachschauen? z.B. osm.org/browse/way/385145640

Gruß, Jan

Hallo,
hier ist etwas schiefgegangen, die Wege habe alle keinerlei Tags. Kannst du da nochmal drüberschauen?

Gruß, Jan

Hi,
could you check the tagging of these two buildings? There is a strange tag.
way/114516260
way/306543826

Cheers, Jan

way/29110888
maxspeed 80 oder 90? Da ist ein tag zu viel.

Gruß, Jan

Hi,
you added many ways with "Highway" or "Higway" tags - could you correct these? Only 'highway' is a valid key.

Cheers, Jan

Hi,
can you check the tagging of this way? Looks strange...
way/470722745

Cheers, Jan

"Then hell break loose" - Just because people remind you on the way things should be done in OSM? Have fun putting tags on nodes - nobody will be able to make any use of them as long as you don't write documentation for it.

The name:fr tag, which is rendered by openstreetmap.fr doesn't contain the Unicode stuff. The default osm.org map shows the Unicode properly, too. But tag is just a collection of Unicode weirdness without any meaning.

And this "joke" now renders on every map as a huge pile of Unicode garbage, gives errors because of incorrect units in the height tag and service_times that don't follow the documented tagging rules.

Hi,
could you check the tagging of this road?
way/46039701

The name tag is somehow strange.

Thanks! I'm sorry for the mistake but I forgot to check the history of the way...

Sure, if it provides additional information, an additional tag makes sense.

As you describe a sub-group of bakeries, I would opt for a tagging like this:
shop = bakery
bakery = boulanger

All the tags listed in this project are well-described in the wiki.

Take the node from this changeset as example: I have absolutely no clue why there is a need to list a single destination 15 times on a simple two-lane road like this.
I strongly suggest to ask the communicty for comments before starting to map so many nodes in such a complicated manner. It would also help if you could provide sample images of the signs you try to map.
