Change subject: Dont wrap IEW with spans when they are in fosterable posns in
tables
......................................................................
Dont wrap IEW with spans when they are in fosterable posns in tables
* On the following wikitext snippet, Parsoid was adding span wrappers
around IEW emitted by the {{WDL}} tpl. These would then get fostered
out and introduce dirty diffs by emitting <span></span> on RTing.
----
{|
|5th {{WDL|7|2|2|3}} || 5 || 7 || 6
|}
----
* This patch makes fixes by not span-wrapping IEW in fosterable posns
in tables.
* Also fixed getAboutSiblings to continue collecting siblings across
IEW gaps when in fosterable position.
* Fixes parsing of above snippet.
* No change in parser test results (TODO: need to come up with a good
test case for this to prevent regressions).
