2017-08-22Bypass asserts in string [] operator for empty stringschromium/3194Ryan Harrison
The previous behaviour of [] on an empty string was to return 0 regardless of the index. We wanted to make this more strict, hence the current behaviour. This has led to a number of crashes due to code depending on the old behaviour. Reverting to the old behaviour until we have time to correct the call sites using empty strings.

2017-08-21Avoid annotation popups to be clipped at page edgesJane Liu
Currently, annotation popups are placed at a fixed location relative to the annotation. If an annotation is too much on the right or the bottom of the page, then its popup will be clipped at the edge of the page. This CL translates the popups appropriately to avoid getting clipped at page edges. Also, if an annotation is at the bottom-right corner of the page, then the popup is placed above and to the left of the annotation, instead of below and to the right of it.

This method duplicates the behaviour of the const [] operator and doesn't offer any additional safety. Folding them into one implementation. SetAt is retained, since implementing the non-const [] operator to replace SetAt has potential performance concerns.
