Using == in a th:with tag on the body element when a layout also has a th:with tag doesn't work

First off thank you for writing this library, it's helpful.

thymeleaf-layout-dialect version 3.3.0 in an application using Spring.

Example "isA = ${ a == b ? true : false}" results in the VariableDeclaration's name being "isA" and the value being "${ a ", which is incorrect.

If the above expression is modified to us 'eq" vs '==' it works fine. The issue also holds true with "!=".

Seems like all equal signs are split not just the first one. (From the VariableDeclaration object):
(name, value) = assignation.stringRepresentation.split('=')

Ah, this might be due to the very naive string processing to extract variables, which is likely related to #222 raised a while ago.

I'm struggling to remember why I may have done my own string processing here instead of finding something in Thymeleaf that can do it - I should be able to hand it off to Thymleaf to resolve this bug 🤔

Sorry I did not see #222. As to handing it off to Thymeleaf, perhaps it's related to how Thymeleaf handles it differently base on if Thymeleaf is used with Spring or not. I think it's OGNL vs SpringEL? Or maybe it was thought it was overkill since it's just about merging them without actually processing them?

For my use I was able to just not use a th:with tag in my layout file to avoid the issue, since it only occurs when merging.

Thanks again for the bug report. Provided I got the test case right then this should be fixed in the next release, 3.4.0, which I hope to release soon.

No problem, and thank you for fixing it so quickly!
