InspectorControls: Custom panel will be placed before Typegraphy panel

[t-hamano]

Description

I hooked up the editor.BlockEdit and added my own InspectorControls as follows.

const withInspectorControls = createHigherOrderComponent((BlockEdit) => {
  return (props) => {
    return (
      <>
        <BlockEdit {...props} />
        <InspectorControls>
          <PanelBody title='My Control'>My Control</PanelBody>
        </InspectorControls>
      </>
    );
  };
}, 'withInspectorControl');
addFilter('editor.BlockEdit', 'wpse', withInspectorControls);

It will be placed after all core panels, i.e. just before the Advanced panel in wordpress 5.8.3

However, for some reason, it is placed between the core panels, i.e. in front of the Typography panel in WordPress 5.9 (RC-1).

I have read the documentation and source for InspectorControls, but I could not understand why this behavior occurs.
Is there any way to place my own InspectorControls after all the core panels?

Step-by-step reproduction instructions

I can still reproduce it with 5.9-RC4.

I have checked this issue again and the block sidebar is now split by tabs, e.g. #45005. Also, in #47105, the styles slot has been added, so this problem should not occur. I would therefore like to close this issue.
