Grieg - Elfin Dance - Staccato + Pedal at the end

[Raagshinnah]

Hello,
I started reading through Grieg's Elfin Dance yesterday (quite an amusing piece:) ) and came across something which is a bit mind-boggling.
The last three measures have one long pedal sign under them, indicating that the pedal should be held throughout those three measures, yet the only notes in them are staccato chords with grace notes before them.

I'm not quite sure how I'm supposed to make something sound staccato when the pedal is held, any ideas on what he meant?
The only possibility that I could think of is that the pedal should be held only for the grace notes and then let go of when the chord is struck, but wouldn't the pedal sign be different if that was the case?

I couldn't find any recordings of it, so I can't really find out by listening to it either :\

I'd also appreciate performance tips for this piece

Thanks in advance

ps: if you need to see the sheet music, here's a version of it (it's not the same as mine, but the pedal indication is there) : https://www.sheetmusicarchive.net/dlpage_new.cfm?composition_id=287

My students have a piece that used this all the time.

In this case, the staccato isn't about the "detached sound."

Use the pedal AND a staccto TECHNIQUE.

What is the result?

A sustained, POINTED sound. You can even do this at a piano dynamic.

It's hard to write about, but think on those terms and it should make sense.

Thanks, I'll give it a try tonight
