Alignment of listed attachments in page options does not work correctly

Problem

When viewing listed attachments in a page, the alignment of the listed bugs is affected (with attachment names missing), if the page tab is moved to right.

Environment

Confluence 8.5.x

.

Steps to Reproduce

1. Create a page with atleast 5 attachments.
2. Click on the three dots on top right and choose "Attachments(5)"
3. View the attachments. The attachment names appear normally.
4. Now adjust the page divider to right to reduce the amount of space for the attachments like in the image:

Expected Results

The names of listed attachments should not be affected and be listed

Actual Results

The names are displayed in an odd way. This behaviour was not noted in older versions such as 7.19.x

Workaround

None
