False-positive SENTENCE_WHITESPACE with two sentences in two arguments of a command

[MrEbbinghaus]

Describe the bug
Two sentences in two parameter fields get checked like they are next to each other, without whitespace, resulting in a false-positive SENTENCE_WHITESPACE.
Both parameters should be checked and at least \caption does not appear inline, so a custom ltex.latex.commands won't help.

\caption[This is a short caption.]{This is the long caption, that is shown below the figure and that can be quite long. It can also contain multiple sentences.}
% gets treated like:
This is a short caption.This is the long caption, that is shown below the figure and that can be quite long. It can also contain multiple sentences.

Expected behavior
Two parameters should be checked as if there were separated by a white space.
I can only think of synthetic situations where this would result in a false-negative, and even then I think treating two parameters as separated by white space is correct in more situations.
