[2.0.73] LuaGuiElement "scroll-pane" with style "deep_scroll_pane" incorrectly renders scrollbar

[Data]

Not sure if it's a bug, or I'm misusing API/base game assets, but here we go

What did you do?

• Start the freeplay with default settings, no mods/space age dlc
• Skip the cutscene
• Run the command (twice to suppress achievements disable warning):

  Code: Select all

  /c
  local frame = game.player.gui.screen.add{ type = 'frame' }
  frame.style.size = 100
  local pane = frame.add{
      type = 'scroll-pane',
      style = 'deep_scroll_pane',
      vertical_scroll_policy = 'always',
      horizontal_scroll_policy = 'never',
  }
  pane.style.horizontally_stretchable = true
  pane.style.vertically_stretchable = true

• Inspect the frame created at top left corner of the screen

What happened?
The frame contains scrollpane, but scrollbar offset too much to the right (see the screenshot attached)

What did you expect to happen instead?
Scrollbar should be within scrollpane

Does it happen always, once, or sometimes?
Always reproducible, style "deep_scroll_pane_with_padding" has the same scrollbar issue

If you run similar code snippet, but with the default style, scrollbar will have correct position (see also the screenshot):

Code: Select all

/c
local frame = game.player.gui.screen.add{ type = 'frame' }
frame.style.size = 100
local pane = frame.add{
    type = 'scroll-pane',
    vertical_scroll_policy = 'always',
    horizontal_scroll_policy = 'never',
}
pane.style.horizontally_stretchable = true
pane.style.vertically_stretchable = true

Thanks for the report however this is not a bug. That style specifically has “scrollbars_go_outside = true” which does exactly what it says.
