JS error: Field IDs contain "%3D" urlencoded equal sign, causing errors

[Ciantic]

Hello

Gutenberg Forms seems to be using some sort of base64 to generate ID's, that doesn't work since Base64 includes = at the end nearly randomly.

E.g.

e48ec1__LS1uYW1lLWU0OGVjMS10cnVlLW5hbWUtbmFtZV9lNDhlYzE%3D

Notice %3D this is causing JS errors.

<!-- wp:cwp/name {"isRequired":true,"label":"Nimi","id":"e48ec1__LS1uYW1lLWU0OGVjMS10cnVlLW5hbWUtbmFtZV9lNDhlYzE%3D","field_name":"name-e48ec1","messages":{"0":{},"empty":"Please fill out this field!","invalidName":"The name {{value}} is not valid!","fieldName":"name"},"condition":{"field":"select-3d4ac9","condition":"===","value":""},"adminId":{"value":"name_e48ec1","default":"name_e48ec1"}} -->
<div class="wp-block-cwp-name cwp-name cwp-field"><div class="cwp-field-set"><label for="e48ec1__LS1uYW1lLWU0OGVjMS10cnVlLW5hbWUtbmFtZV9lNDhlYzE%3D">Nimi <abbr title="required" aria-label="required">*</abbr></label><div class="cwp-field-with-elements"><input id="e48ec1__LS1uYW1lLWU0OGVjMS10cnVlLW5hbWUtbmFtZV9lNDhlYzE%3D" aria-label="Nimi" data-cwp-field="true" name="e48ec1__LS1uYW1lLWU0OGVjMS10cnVlLW5hbWUtbmFtZV9lNDhlYzE%3D" title="The name {{value}} is not valid!" data-errors="{&quot;mismatch&quot;:&quot;The name {{value}} is not valid!&quot;,&quot;empty&quot;:&quot;Please fill out this field!&quot;}" type="text" data-rule="false" placeholder="" required/></div></div></div>
<!-- /wp:cwp/name -->

It seems to be generating these IDs somehow, even if I remove %3D from the code they come back.

JS error they give looks like this:
