📄 Description

This fixes an issue were overwriting parts of a row would only trigger
that specific portion of the row to be redrawn. This isn't just
problematic for combining characters, but also for things like
the new TestDbcsBisectWriteCells test introduced in #13626.

Benchmarks showed no impact on performance whatsoever.

Validation Steps Performed

  • Pick this commit into #13626
  • Run the TestDbcsBisectWriteCells test and break before OpenConsole exits
  • A correct "QいかなZYXWVUTに" output is visible ✅
