Description

With #16829 and #17739 we can now display files beyond MAX_GIT_DIFF_FILES and MAX_GIT_DIFF_LINES, and add review comments on them.

But the files view initially only loads the first page of files, and only those files that don't exceed the max lines.
So direct links (e.g. when navigating from the conversation view) to comments that are added on such files do not work.

Example:

• https://try.gitea.io/jpraet-org/test-repo/pulls/1/files#issuecomment-112226 (a comment on file 105, but only 100 are loaded)
• https://try.gitea.io/jpraet-org/test-repo/pulls/2/files#issuecomment-112222 (a commend on a large file)

I don't think we can fix this very easily.

It depends on our frontend refactoring to provide a better frontend component mechanism.

It depends on our frontend refactoring to provide a better frontend component mechanism.

So, the front-end can detect that isssuecomment-xxx is specified in the URL, and it can very easily check if it's in the DOM.

When the code knows that it's the DOM, do nothing, but if it sees that isssuecomment-xxx isn't in the dom, and it sees that the show more files button is present(and code will make a guess that this comment is in those files), then it could show a popup:

"It seems like that a specific comment should be shown, but the comment could not be found in the loaded files. Would you like to load the additional files of this PR and see if it's present in those" (something along those lines).
