From v2.4.2, slider nestable and accordion nestable no longer init when inside component in the block editor.

To reproduce..

- add either of those elements in a component
- enable ‘Use in block editor’.
- inside the block editor, add in that new component.

My understanding of the issue is due to it calling `.get()` on `window.tinymce8 || window.tinymce` whenever `bricksIsFrontend` is false. Inside the block editor’s iframe neither exists.

Console..

bricks.min.js?ver=1790641088:1 Uncaught TypeError: Cannot read properties of undefined (reading ‘get’)
