Eclipse hangs when opening a minified CSS file in CSS Editor

When I open a minified CSS file, i.e. with one very long line (e.g. 80k characters), Eclipse hangs with 100% CPU load.

The severity is different for different files of similar length, probably depending on the content. For some, Eclipse hangs for about a minute, which allows you to close the editor without killing Eclipse, e.g. fontawesome.min.css from https://fontawesome.com/download .

Others, like a proprietary file that I can't share, make Eclipse sleep for at least one hour (maybe forever).

While I can consciously avoid opening these files, it is especially annoying in a global search, when clicking next takes you to such a file without a warning.

When I open the same file in the plain text file editor, the CPU load goes up to 100%, too, but Eclipse gets responsive again much faster.

レポートにある fontawesome.min.css を CSS Editor で開いてハングを再現し、プレーンテキストエディターおよびグローバル検索からのナビゲーションと比較します。CSS Editor の起動経路を追跡し、長い行のファイルで応答性を測定します。完了の条件は、Eclipse が応答しなくなることなく、これらのファイルを開くか検索から到達できることです。
