disableToolbarButtons() fails when toolbarButtons is null in RichEditor

I’m running into an issue with RichEditor when using disableToolbarButtons() without defining any toolbarButtons.
If no default buttons are set,

$this->toolbarButtons

$this->toolbarButtons

$this->toolbarButtons

$this->toolbarButtons is

null

null

null

null, and

disableToolbarButtons()

disableToolbarButtons()

disableToolbarButtons()

disableToolbarButtons() calls

array_reduce()

array_reduce()

array_reduce()

array_reduce() on it, which throws:

array_reduce(): Argument #1 ($array) must be of type array, null given

This happens in the InteractsWithToolbarButtons trait (line 33).

To Reproduce

RichEditor::make('content')
  ->disableToolbarButtons([
    'attachFiles',
  ])
  ->required(),

RichEditor::make('content')
  ->disableToolbarButtons([
    'attachFiles',
  ])
  ->required(),

RichEditor::make('content')
  ->disableToolbarButtons([
    'attachFiles',
  ])
  ->required(),

RichEditor::make('content')
  ->disableToolbarButtons([
    'attachFiles',
  ])
  ->required(),

Anyone else having the same issue?
