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.

Reproduce el bloqueo abriendo fontawesome.min.css del informe en el CSS Editor y compáralo con el editor de texto plano y la navegación desde la búsqueda global. Sigue la ruta de apertura del CSS Editor y mide la capacidad de respuesta con el archivo de línea larga; se considera terminado cuando estos archivos se pueden abrir o alcanzar desde la búsqueda sin que Eclipse deje de responder.
