Writer field cursor jump

Situation: Editing a writer field in the panel drawer which contains text (image caption field).

Action: When I place the cursor in front of the first character (or any position) and start typing the cursor jumps to the end of the text.

Kirby: 3.5.3.1

Blueprint:

name: field.blocks.image.name
icon: image
preview: image
fields:
  image:
    label: field.blocks.image.name
    type: files
    multiple: false
    width: 1/2
    layout: cards
    size: small
    image:
      back: black
    uploads:
      template: image
  caption:
    label: Caption
    type: writer
    icon: text
    width: 1/2
   … etc

It seems that setting inline: true instead of the default false prevents this behaviour.
Also, without inline: true any text after a hard return isn’t displayed at the front-end.

I can reproduce this issue and seems to be a bug.
