The highlighted text cannot be saved

The edited highlighted text cannot be saved, and the highlighted text content disappears after the windterm program is closed.
How to tile multiple session tags? I need to tile multiple sessions at the same time. Multi-execution mode similar to mobaxterm.

The issue names no source files, tests, or entry points. First clarify whether the requested work concerns saving highlighted text, tiling session tags, or both, then reproduce the behavior in WindTerm; done means the agreed behavior is implemented and remains correct after closing and reopening the program.
