Ctrl + S in structure field containing date fields clears content

[bezin]

Description

I have a custom block with a structure field, that has several fields (text, color, list, two date fields)
When I edit a structure item and hit CTRL+S, the structure form is closed and I see the editing mask for the block again, but all content is gone – at least visually. When I close the drawer and save the changes, everything works as expected (the content is still there incl. my intentionally made changens).

This does not happen, when I exclude the date fields. However, the changes I made were not in the date fields, but in a text field.

Expected behavior
I expect CTRL+S to close the structure field edit mask and return to the block edit mask without loosing the content.

@bezin Could you please share your blueprint?

Sure thing, here you are:

# site/blueprints/blocks/timeline.yml
name:
  en: Timeline
  de: Zeitleiste
fields:
  headline:
    label:
      en: Headline
      de: Überschrift
    type: text
    width: 1/2
    required: true
  phases:
    label:
      en: Project phases
      de: Projektphasen
    columns:
      title: true
      color: true
      from: true
      till: true
    type: structure
    fields:
      title:
        type: text
        required: true
        width: 1/2
      color:
        label:
          en: Color
          de: Farbe
        type: color
        required: true
        width: 1/2
      from:
        label:
          en: From
          de: Von
        type: date
        calendar: false
        required: true
        width: 1/2
      till:
        label:
          en: Till
          de: Bis
        type: date
        calendar: false
        required: true
        width: 1/2
      objectives:
        type: list
        required: true

When you use it like this, ctrl + s clears the data in the view. However, when you uncomment from and till (both, one is not enough), everything works as expected.

I ran into the same problem with this blueprint. While working in the nested structure, it overrides structure 1 when I'm in a field and press cmd+s.

title: Nested structure

fields:
  structure1:
    type: structure
    label: Structure 1
    fields:
      title:
        type: text
      structure2:
        type: structure
        fields:
          title:
            type: text
          date:
            type: date
            default: today

PHP: 8.3.7
Kirby: 4.2.0

Edit: When I remove the datefield, everything works the way it should work
