This commit enhances the dom_oracle by introducing a mechanism to recompute potential relations during a DOM walk. When querying relationships between values, the system now re-evaluates promising edges, potentially discovering more accurate relationships. This change aims to improve the precision of value-relation analysis, addressing a bug where specific relations were not being correctly identified.
