Sort dropdown flashes when loading issue/pr list

Description

When viewing the issue or pr list, there is a short flash of the sort dropdown content.

Can you reproduce the bug on the Gitea demo site?

Yes

1.19 is not affected, so this is a very recent regression. @wxiaoguang might have been from one of your recent PRs.

I guess it's related to

• Fix dropdown direction behavior #23806

the initial purpose is for:

• Some problems of dropdown menus #23625

let me see

Removing the "left" style of the "menu" resolves the flash. If you don't mind, I will make the fix in #23856 together, to save time.

Don't mind, but there might be more similar cases, should grep for them.

Actually, I do mind a bit as there is no relation, so separate PR might be good :)

Nope, there won't. The whole story is:

Since the popup position calculation is not stable, so I think it's good to make the "Sort" menu always have the "left" position. However, the "left" style have "display: flex", it should be used with "hidden" together. I didn't find the flash because my window is not large enough during my test. To make things simple, remove the "left" style.

So, it's a simple fix. I just pushed ... and I will update the description.
