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.

在 CSS Editor 中打开报告中的 fontawesome.min.css，以重现卡顿，然后将其与纯文本编辑器以及从全局搜索进行导航的情况进行比较。跟踪 CSS Editor 的打开路径，并测量长行文件上的响应性；完成的标准是：可以打开这些文件或从搜索结果访问这些文件，同时 Eclipse 不会失去响应。
