Problem with code area and block palette with specific project #9199

Open

Description

With project https://scratch.mit.edu/projects/1387832458/editor/ there are two problems in Chrome:

  • the "hide block palette" add-on doesn't work (the palette stays closed), see initial part of the attached video
  • when I drag the scripts in the code area I see they flickering and jumping to different positions, see final part of the attached video

With other projects, e.g. https://scratch.mit.edu/projects/1380774466/editor/, everything works fine instead.

I'm using this settings scratch-addons-settings-2026 10 05.json

Steps to reproduce

  1. import settings scratch-addons-settings-2026 10 05.json
  2. open project https://scratch.mit.edu/projects/1387832458/editor/
  3. try to open the block palette by hovering the category icons or clicking them: it doesn't open
  4. drag the scripts of Sprite1: they flicker and jump around.

    I have to withdraw this issue: same problem in Scratch without enabling ScratchAddons

    I found the same problem with project https://scratch.mit.edu/projects/1388834350/editor/. It works well in Scratch, but shows flickering and locked block palette when ScratchAddons is enabled. See attached video https://github.com/user-attachments/assets/42d31799-3b9d-4d28-afc7-067f020872b4
