Backport PR #24654: Don't manually invalidate cached lines in _update_transScale

ksunden · rcomer · commit 8d8d3f5c11a6 · 2022-12-10T11:07:32.000Z
Manual backport required due to simple conflict caused by the first removed line being different in main and v3.6.x, having previously been modified at #24634.
