Reusable Block within Query Template

Is it possible to use a Reusable Block within a Query Template? I am testing this out and my Gutenberg screen just freezes when I add one to a Query Template. The test reusable block is simply a Heading using Dynamic ACF data (so it is not complex). I wait for the screen to unfreeze - but it does not and I have to refresh the page (and WP goes back to the last saved version of the page before I inserted the reusable block).

Hi @bmc38119,

Indeed, I have been able to reproduce this on my end and can confirm that something is going wrong.
Moving this to confirmed bugs.

Please bear with us while we find a solution to this.
Thanks for the report and sorry for the inconvenience.

Hi @bmc38119,

This should now be fixed in version 1.2.5.
Please let me know if this is the case on your end.

Once again, thank you for the report and sorry for the inconvenience.
