electron-rebuild properly rebuilds better-sqlite3 on Windows, but skips the rebuild on Linux

[renkei]

Node.js 14.15.4
electron 12.0.0-beta.18
electron-rebuild 2.3.4
better-sqlite3 7.1.2

On Windows, better-sqlite3 is built against Node 14 (windows-build-tools with Python 2.7 are properly installed) and rebuilt against electron 12 using electron-rebuild. The resulting electron app works as expected.

On Linux (Arch Linux, same versions as above) better-sqlite3 is not built but installed via a prebuild binary. When I try to start the electron app with that binary I get the expected NODE_MODULE_VERSION mismatch error:

Error: The module '/home/renkei/Development/MyApp/node_modules/better-sqlite3/build/Release/better_sqlite3.node'
was compiled against a different Node.js version using NODE_MODULE_VERSION 85.
This version of Node.js requires NODE_MODULE_VERSION 87.
Please try re-compiling or re-installing the module (for instance, using `npm rebuild` or `npm install`).

So, I run electron-rebuild like I do on Windows but on Linux nothing happens. After the log message Searching dependeny tree
I get immediately Rebuild Complete. The same happens when I use option -f or -w better-sqlite3 or both.

When I export DEBUG=* for more debug output I get without option -f:

Searching dependency tree 
electron-rebuild skipping: better-sqlite3 as it is already built +52ms
✔ Rebuild Complete

and with option -f:

Searching dependency tree 
Building module: better-sqlite3, Completed: 0 
electron-rebuild assuming is prebuild powered: better-sqlite3 +0ms
electron-rebuild triggering prebuild download step: better-sqlite3 +0ms
Building module: better-sqlite3, Completed: 0 
electron-rebuild built: better-sqlite3 +106ms
✔ Rebuild Complete

Any idea, why the the recompile step is not properly triggered?

I've solved this with a postinstall script in package.json that runs electron-rebuild on Windows and a self-made shell script on Linux that executes npm install better-sqlite3 again, but this time npm is re-configured to build directly for electron, like suggested by the electron documentation as an alternative to electron-rebuild, works perfectly for me.
