Achievement Tabs delete written Comment

[SporyTike]

Describe the bug
Since a few days we now have a new achievement page that has tabs for Comments, Recent Unlocks and Changelog split. Today I realized that acomment you write does not get temporarily saved when switching the tabs meaning if you swap back to the Comments section, whatever you wrote but not submit yet is just deleted.

To Reproduce
Steps to reproduce the behavior:

1. Visit any achievement page
2. Write any comment BUT DO NOT submit it yet
3. Switch to Recent Unlocks or Changelog
4. Switch back to Comments
5. Your comment your were about to post is gone and needs to be rewritten

Expected behavior
In my opinion the text you previously wrote should still be there after switching tabs. There are several reasons why people could switch tabs mid-writing. For example they want to reference to another user who got an unlock and switch to the tab to make sure they spell the name correctly, or they want to mention a recent change that happened and want to check the date or time when it happened. There is no warning that the message will be gone and it is frustrating if you write like 2 minutes of a message just to have it disappear the next second and needing to rewrite it.

Hii,
If I understand correctly, the comment draft is lost when someone is switching between the Comments because the text isn't being preserved in state. I think this could be fixed by saving the comment text in component state or local storage before the tab switch. It would be restored when the user switches back.
Could I be assigned to this?

Hi! Yes, please feel free to take it. It should probably follow an implementation pattern similar to #4667 (maybe reusing the hook this PR introduced).

Hi, I have been taking a look into solving issue but I wanted to clarify something.

I know the issue refers to the achievement page comments with the tabs in:
https://retroachievements.org/achievement/243928

But should the solution also cover the comments list page such as:
https://retroachievements.org/achievement/243928/comments?page=1

Its technically a different page without the tabs but the same comments. It could be a bit strange if the comments persist on the first page I mentioned but not the other.

Yes, ideally the solution covers both.
