Problem: When opening a new tabpage, extui windows are initialized with
their default config. Window visiblity/dimensions on other
tabpages may get out of sync with their buffer content.
Solution: Copy the config of the window to the new tabpage.
No longer keep track of the various windows on each tabpage.
Close windows on inactive tabpages instead (moving them could
be more efficient but is currently not supported in the API).
