}Reproduction steps
A lesser used but valid syntax of erb is <%== which will mark the passed string as html safe. Rails documents it at the bottom of https://guides.rubyonrails.org/active_support_core_extensions.html#safe-strings, although I'm not sure if this is rails specific or not. Could very well be erubi only.
ruby-lsp fails to consider the second equal sign, showing the code like this:
A fix seems rather straightforward but erb highlighting has no tests and I don't really understand these gramar files so I'm not very confident in my change. I can open a PR if it looks reasonable and no tests are fine.
