[Feature request/Bug fix] InnerBlocks template doesn't update

Hey guys,

Loving the new release so far, although I am having an issue with the InnerBlocks template not updating.

Please see example;

Inside my block template

<?php 
$columns = get_field('number_of_columns');
$align = get_field('align');
$template = array();

for($i = 0; $columns > $i; $i++):
    array_push($template,  array( 'core/column', array(), array()));
endfor;

?>

<div class="row row__<?=$align?>">
    <h3>Columns Block</h3>
    <InnerBlocks template="<?= esc_attr( wp_json_encode( $template ) ) ?>" templateLock="all" />
</div>

I have a range field which lets you set a number between 1 and 12 (the number of columns). I am then using a for loop to build the InnerBlocks template. This does work however, the changes are 'live'. It requires the user to refresh the page. I'm assuming this is something to so do with React not compiling properly.

Is there an easy fix for this or is this not possible? From my side this would be very useful since we are building a custom Columns / Column block for our theme.

As you can see below it does work, although you have to update the post and refresh the page to update the template.

Start with the InnerBlocks template example in the issue and reproduce the behavior in the WordPress editor using the PHP loop and range field. Verify whether changing the column count updates the template without saving and refreshing the post. Done means the template reflects the changed value live, or the issue documents a confirmed platform limitation.
