Seen indicators overlap right-to-left texts

### Steps to reproduce

In newer versions of Element, Bidirectional text support thankfully has improved and RTL languages like Farsi are shown from right to left correctly.

The only issue that just noticed today is that, in the Threads panel, the seen message indicator overlaps the right-to-left texts.

1. Write a Farsi text in a thread
2. Open Threads panel
3. Let some people in the room see the message
4. The small profile pictures overlaps the beginning of the text

### Outcome

#### Issue

The issue is shown in the screenshot below, as you see, small profile pictures covers the text:
