Why is wordpress suddenly stripping away all newline characters and how to disable this?

I’ve spent about 3 hours trying out various functions to figure out why the newline characters are being removed every time I save.

How do I figure out why is wordpress suddenly stripping away newline characters? I have not installed any plugins. How can I get newline characters to show up on my site without converting all blocks to HTML and modifying everything in code?

Inline Styles on all native blocks

Is it possible to apply inline styles to all blocks via filters? Or do only some blocks support it? basically I want to add the ability of adding a background image to a single column.
So I added an extra attribute to store the background img url (named backgroundImg) and tested that its saved.

I am trying to use blocks.getSaveContent.extraProps to apply the background image to the inline style like so..

if ("wp-block-column" === props.className) {
    return lodash.merge(props, {
        style: {
            backgroundImage: "url(" + props.backgroundImg + ")",

When I run this however the background IMG url is ‘undefined’. However I have tested and know that props.backgroundImg is being saved. I can add more of my code as needed, but any ideas on why it isn’t applying the saved url?

Where to find documentation for CPT block template? (PHP)

I have been searching for a day and still carn’t seem to find the right documentation for what arguments I can pass to core components when attempting to configure a CPT block template in php. This is what I have but I want to take this further by nesting buttons and custom html etc. but carnt find the docs I need.

'template' => array(
    array( 'core/columns', array(), array(
        array( 'core/column', array("width" => "60"), array(
            array( 'core/image', array() ),
        ) ),
        array( 'core/column', array("width" => "40"), array(
            array( 'core/image', array() ),
            array( 'core/heading', array(
                'placeholder' => 'Add a inner paragraph'
            ) ),
        ) ),

Found everything needed to create bespoke blocks in JSX but blegh, Not got the time to learn the wizardry ways of JSX just yet and I dont really want new blocks just want the existing one bound as a template to a custom post type.

A good way to example my question, how did this person find the answer on how set the width of this template columns.

How to set column widths in a CPT block template?

How did the person find this answer ? did they have to dive in to the JS scripts of the component and work it out or is there some documentation on this or am I missing something all together.

Any help would be greatly appreciated.
