Updated row and spacer handling for Escalator (#11438)
Updated row and spacer handling for Escalator.
Main changes:
- Spacers are only maintained and checked for rows that have DOM
representation, and not at all if there is no details generator. This
gives notable performance improvements to some particularly large Grids
- Escalator no longer tries to trim away any rows that don't fit within
the viewport just because a details row gets opened in Grid. This leads
to some increase in simultaneous DOM elements, but simplifies the logic
considerably. For example opening or closing details rows doesn't
require checking the overall content validity beyond the details row
itself anymore, but some repositioning at most. There are also no longer
any orphaned spacers without corresponding DOM rows.
- Spacers are better integrated into the overall position calculations.
- Some public methods that are no longer used by Escalator or have
changed functionality or order of operations. Any extending classes that
tap into row, spacer, or scroll position handling are likely to need
reworking after this update.
- Auto-detecting row height is delayed until Escalator is both attached
and displayed.
Improvements to detail row index handling. (#11345)
- Escalator should notify when an existing details row is moved to a new
index.
- Grid and DetailsManagerConnector should update their internal indexing
when details manager index changes in Escalator.
Fixes to displaying Grid in a detail row. (#11147)
- Multiple headers shouldn't stack behind each other.
- Body rows shouldn't get stuck to default row height.
- Compatibility version's hidable row selector shouldn't try to
calculate row heights based on rows that haven't been added to DOM yet.
Fixes #7674
Escalator supports adding spacer elements into DOM. (#16644)
This is the first step towards Grid's details rows: Escalator puts spacer elements
in the DOM, and is able to scroll around with them. The spacers are put in their
correct locations, but they will not affect the normal row elements in any way at
this time.

Add support for changing the default row height in escalator (#12645)
Since this is quite the change, I've taken the opportunity to rewrite smaller
adjoining pieces to make more sense. Move methods from classes, and so on.
These changes are, however, only on the code level, no other functionality will
be introduced by this patch.
