Description

When clicking on an image in a chat, it opens, but is blurry. This often makes text (very) difficult to read.
Today I finally found out that the image is only blurry when I have zoomed the interface/text (either zoomed in or out). It is sharp when zoom is neutral. However, I need a custom interface/text zoom level (which is thankfully remembered between sessions).

Current Behavior

When clicking on an image in a chat, it opens, but is blurry. This only seems to be the case when interface/text is zoomed in or out (i.e. not neutral/reset).

Expected Behavior

I expect the an image to be shown without scaling, regardless of / independent from the current interface/text zoom level. Possible exception: scale down large image that would otherwise not fit on screen. Possibly allow zooming in/out an opened image, independent from the interface/text zoom (per viewing, and/or as remembered setting between sessions).

BTW: The current shortcut for "Zoom in" is "Ctrl + Shift + =". That is fine, but please also support the shortcut without Shift. That is very widely adopted behavior. Otherwise at least add shortcut "Ctrl + Shift + -" for "Zoom out". It is very un-intuitive to have to press and release Shift while looking for the best zoom level.

No source files, tests, or entry points are named. Start by reproducing the image viewer with interface zoom set above and below neutral in the Rocket.Chat desktop app, then verify that opened images remain sharp and that the requested zoom shortcuts behave as expected.
