Just a minor bug here.

**Repro Steps:**

- Enter a topic with a few existing replies
- Hit reply on the first post
- Scroll down past the last post with the composer open

**Additional notes:**

- Can reproduce in desktop Safari, Chrome and Firefox
- Browser window must be small enough to where the composer is touching the edges of the window
- It seems to trigger when topic-progress indicator detaches from the composer and docks to the last post

Seems to go away with:

```plaintext
#topic-progress-wrapper.docked {
   right: 1px;
}

```

**Illustration:**

Make the browser a bit bigger, then? 😉

🤣 Unfortunately that would require buying a new computer! On a 13" MacBook Pro, the composer touches the edges of the window at maxed browser size.

Here’s another weird thing that can happen because of it:

With that said, this is a minor thing that the majority of users probably won’t encounter.

Maybe @awesomerobot can take a look at some point.

So turns out the topic progress bar was ~2px wider than its container (likely because of the border?), so when at `right: 0;` and at X/X progress it produced a slight horizontal scroll. The solution was to subtract 2 from the width calculation.

FYI @sam this was the same issue you were seeing.
