Summary: When the zoom +/- buttons are used, if a manually entered zoom value was used, that value is lost.

Impact: The only way (known to the user) to bring up the zoom value entry field is to first press either the zoom +/- buttons. When this is done, it also moves to the next zoom preset and you lose your custom zoom value.

Expected result: There is some way to view your zoom setting without changing it. Also, if a custom zoom setting has been entered manually, the zoom +/- buttons will either increase or decrease incrementally from that, or at least keep that last setting in the cycle of zoom values. Maybe bringing up the zoom slider / zoom value popup when you <right click> the zoom +/- button without changing the current zoom setting would solve part of the issue.

Observed Result: Currently the only way to see the zoom value appears to be by first pressing the zoom +/- button, but this also changes the zoom setting at the same time. Once changed, you need to manually enter your zoom value again. If you don't remember which value you entered last, you might then need to try several different zoom values to get back to the one you were using.

Example: I wanted the page zoomed slightly larger than the "Fit-to-width" size (158%) . I manually set the zoom to 165%. After that, when I pressed the zoom + button, it drops back to 158%. Some custom zooms jump to the next highest detent. I haven't figured out the pattern when it jumps up or down from the current setting, but either way, it drops my manually entered zoom and I see no way to confirm my zoom before changing it.
