Grid: enabling grid after running without grid buts sidebar width very large #79020
Description
Steps to Reproduce:
- run from a fresh user data dir without grid layout enabled (e.g. using stable)
- run over same user data dir out of master
=> 🐛 the sidebar width is half the window width
I think to offer a smooth transition, we need to find a way to migrate the sizes for the old layout to the grid layout.
