 * **Fixes badly initialized Formula** Problem: YoloX contain new types of elements, when loading a document that contain formulas a new element of that class
 should be generated, however the Formula class inherits from Element instead of Text. After this change the element is correctly created with the correct class
 allowing the document to be loaded. Fix: Change parent class for Formula to Text. Importance: Crucial to be able to load documents that contain formulas.
+* **Fixes pdf uri error** An error was encountered when URI type of `GoToR` which refers to pdf resources outside of its own was detected since no condition catches such case. The code is fixing the issue by initialize URI before any condition check.
