screen's maximum supported length for OSC sequences is around 768 characters. After that, parameters within the sequence begin to appear literally on the screen.

The OSC 8 hyperlink feature (see via bug 50952) recommends that URLs of length up to 2083 bytes, an "id" of up to 250 bytes, and the necessary boilerplate (the ";id=" + ";" characters) are supported.

In order to at least silently ignore OSC 8, without causing display problems if an app emits a long URL, could the OSC size limit please be increased to at least about 2400?

(Note: upload size limit is set to 16384 kB, after insertion of the required escape characters.)
