Page number should update after font size change (to maintain approximately same place in chapter, and avoid out-of-bounds) #220
Description
Affected Version
0.11.2
Describe the Bug
After changing font size, reader mode tries to stay on the same numbered page rather than the same location in text (or approximating based on the fraction of the way through the current chapter).
This results in moving to a different part of the text, and perhaps an "out of bounds" error if the font was made smaller and reader was previously near end of a chapter.
Expected Behavior
After changing font size, the reader re-indexes the current chapter. Should jump to approximately the same part of the text rather than keeping the literal page number (within chapter) the same.
