1778644 - [CTW] Treeherder tables are treated as layout tables

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[James Teh [:Jamie]]

STR (with NVDA + CTW):

1. Open https://treeherder.mozilla.org/jobs?repo=try&selectedTaskRun=boxco99xQLiWqSj6L1hzqQ.0&revision=6664ba8aa4f29c6ad352243cfee1646dd09b12a8
2. Press t to navigate to the table.
   • Expected: NVDA should move to the jobs table.
   • Actual: NVDA says: "no next table"

This doesn't happen when CTW is disabled. My guess (not yet verified) is that when the table is added to the tree, it is considered a layout table, but it then mutates such that it's not a layout table. We aren't handling that mutation correctly.

This will probably be fixed by pushing a cache update for layout-guess if children are added or removed from the table.
