Undefined array key 0 when chosing a grouping field

Problem/Motivation

Undefined array key 0 in Drupal\leaflet_views\Plugin\views\style\LeafletMap->setOverlaysGroupingElement() (line 530 of /path_to_site/web/modules/contrib/leaflet/modules/leaflet_views/src/Plugin/views/style/LeafletMap.php). =>

Steps to reproduce

Go to Format:Leaflet Map > Settings
Then in Overlays - Leaflet Grouping section chose a grouping field

Proposed resolution

Line 530 is about the Disabled Layers form field

          '#options' => $overlays_options,
(L530)    '#default_value' => $this->options["grouping"][0]['overlays_options']['disabled_overlays'],

thanks @erwangel for reporting this.
I could reproduce. Indeed this can happen the first time a new Leaflet View style is set, as the grouping options don't have pre-defaults.
Please Qa and Review the attached patch that should fix this ...

Never mind. Already moved forward on this.

Thank you Iramair. You've solve it so quickly that I didn't have time to try the patch but I updated to 10.3.7 and indeed there is no more warnings.
