Compat issue: <div><table><svg><foreignObject><select><table><s>

[Ms2ger]

Chrome: Firefox: Not sure who's right.

I think Firefox is correct. At least I can't find a reason why foreignObject would be popped from the stack of open elements.

@hsivonen @mfreed7?

[annevk]

I've changed my mind. WebKit and Chromium are correct.

Reasoning:

• <div> gets put on the stack
• <table> gets put on the stack
• <svg> gets foster parented and put on the stack
• <foreignObject> gets put on the stack
• <select> gets put on the stack
• <table> implies </select> which resets the insertion mode. That walks up the stack until it finds <table> which sets the insertion mode to "in table". Then <table> in that mode causes everything up to and including the prior <table> to be popped from the stack.
• <s> gets foster parented.

Stepping through the spec I reach the same conclusion.

Notes

```

stack: html,body,div im: in body stack: html,body,div,table im: in body -> in table | |

|

stack: html,body,div,table,svg im: in table Parse error. Enable foster parenting, process the token using the rules for the "in body" insertion mode, and then disable foster parenting. stack: html,body,div,table,svg,foreignObject im: in table, using the rules for in body; Process the token according to the rules given in the section for parsing tokens in foreign content. dom: | | | |

|

stack: html,body,div,table,svg,foreignObject,select im: in table, using the rules for in body -> in select in table dom: | | | |

|

Pop elements from the stack of open elements until a select element has been popped from the stack. stack: html,body,div,table,svg,foreignObject Reset the insertion mode appropriately. im: in table Reprocess the current token. Pop elements from this stack until a table element has been popped from the stack. stack: html,body,div Reset the insertion mode appropriately. im: in body Reprocess the token. stack: html,body,div,table im: in body -> in table dom: | | | |

|

| stack: html,body,div,table,s im: in table Parse error. Enable foster parenting, process the token using the rules for the "in body" insertion mode, and then disable foster parenting. dom: | | | |
