• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

The HTML spec has been updated to detect encountering a <template> inside of a <select> which is inside of a <table>. In this case the <select> will cause the parser to be in "InSelectInTable" mode. Thus when the <template> closes, it should return to that mode.

The fix here is that resetInsertionModeAppropriately must continue looking up the stack if the first node is <select> to see whether the <select> is inside of a <table>

Oops, I need to wrap this entire block with ENABLE(TEMPLTE_ELEMENT).
Will do that before landing it.
