Apostrophe missing in message text with variable

[m-i-0]

Simple issue - if text contains apostrophe and has placeholder for variable, the apostrophe wont display and variable wont be replaced until second apostrophe is added, which is error prone (because without variable, only 1 apostrophe is needed):

messages.properties:

test.simple = Lorem i'psum
test.variable.nok= Lorem i'psum {0}
test.variable.ok = Lorem i''psum {0}

test.html:

<span th:text="#{test.simple}"></span>
<span th:text="#{test.variable.nok(${val})}"></span>
<span th:text="#{test.variable.ok(${val})}"></span>

Tested on Spring Boot + Thymeleaf 2.7.14 - 2.7.16.
