Basic Info

• Reproduction Link: https://arco.design/mobile/react/arco-design/pc/#/doc/changelog

What is expected?

The description of the update log is displayed abnormally. Normally, it should display 2 lines of text, but now the text of line 2 and line 1 overlaps

Steps to reproduce

Open https://arco.design/mobile/react/arco-design/pc/#/doc/changelog to view the changelog of version 2.27.0 and view the first text of the Bugfix
