Loading blocks from CKEditor not working

Problem/Motivation

Hi,

I followed the different steps to create a tooltip from CKEditor from a custom block.
The "From Block" select list field is always empty even if many custom blocks exist.

Steps to reproduce

Follow the different steps to install the module, to create a custom block and to use it via a tooltip from CKEditor.

Proposed resolution

File EditorTooltipDialog.php, line 86:

$tooltip_blocks = $content_blocks = [];

I don't know why this line has been added, it just empties the 2 db requests made just above to retrieve the custom blocks.

Maybe a remain from some testing.

Remaining tasks

Remove that line/review the file
