ODS with the issue

1. Open attached file
2. In the focused sheet 07, input 30 to G4 and save or save as

Seems to be hanging.

The file was originally an xlsx file, but I am unable to make a reproducer with it.

Before commit d7214aba95bbdcbd40e87ef50fc66f2e2ec4f5ff the saving happens in a normal way, albeit a bit slowly, taking about 10 secs for me. Commit verified in both Linux and Windows 24.8 repos.

I get it that the commit adds new functionality, so will not call this a regression.

Perf flamegraph of saving

Unfortunately one interesting block in this flamegraph is just "unknown".

Perf flamegraph of saving

Redone flamegraph in Hotspot as the Flamegraph script is now broken with our setup.
