Two Image Occlusion issues

[jcznk]

Tested and reproduced on both 24.06.3 and 24.11, Windows 10, Qt6. Both issues are related to the Image Occlusion editor (Add window).

• Add window: If you toggle the mask editor and navigate to the fields section, you cannot scroll using the mousepad or the mouse scroll wheel. If you attempt to, the "mask editor" will be scrolled instead.
  Short demo:

  (Steps: 1. toggle the mask editor, 2. scroll with the mouse wheel, and nothing seems to happen, 3. when I go back to the mask editor, the image has been scrolled up.)

• Add window: If you navigate to the fields section, add one or more tags, return to the mask editor, and then go back to the fields section, the tag(s) will "disappear." If you add the note after the tags have "disappeared", they will still be included in the newly created note. However, if you re-focus the tag bar before adding, the tags will be lost.

• Also:

  1. Add an Image Occlusion note with one or more tags.
  2. After adding the note, don't close the Add window. Select or paste an image and create some masks.
  3. Go to the fields section, delete the tag(s) from the previous note, and add one or more new tags.
  4. Return to the mask editor.
  5. Go back to the fields section — the editor will display the tags from the previous note instead of the correct ones.
  6. As before: if you simply add the new note, the correct tags will be included. However, if you re-focus the tag bar before adding, the tags from the previous note will be added instead.
