[Steps]

    1. Launch calc

    2. Input 1/2/2001 in a cell

[Problem]

    The 1/2 is autocorrected to small fraction style but obviously it is
    expected be a style of Date in the context.

    The problem is caused by autocorrection always getting advantage here when
    typing a key after '2'.

    It causes something like 'conflict' between choosing Date and fraction,
    and become a more ditinguishing issue when people want to type a date in
    Calc cell.

[Extra Information]

    The issue appears since replacement table containing 1/2, 1/4, 3/4 (or
    even more in the future) there mapping to small fraction text.

    It could be a better choice to put the fraction autocorrection as a
    checkbox instead of a replacement mapping, and checked off by default in
    Calc.
