            Data race about map::operator[]

            Is there any potential problem in this code snippet?

            operator[] of associative and unordered containers is not specified to be safe from data races if called without synchronization in multiple threads. See [container.requirements.dataraces]/1.

            Therefore your code has a data race and consequently undefined behavior. Whether or not a new mutex is created doesn't matter either.

            Issue:

            Custom functions can only return values (strings, numbers, etc.), not formulas. A "formula" returned by a custom function will just be interpreted as a string starting with =.

            Related requests in Issue Tracker: Workaround 1:

            Modify your custom function so that it just returns the url part (i.e. #gid=...) and use that returned value in a =HYPERLINK() formula which is called conventionally by your sheet:

            Answered 2022-Feb-08 at 20:21

            Hiding the error on your reply button sample... I see the following:

            the input and form are all children of an unnamed div with a default width (none specified).

            If you set that parent's width to 100%, then your input, which also lacks a width: 100%, will stretch, like so:

            You will then need to define what you want to do with your gray chat box but, just keep in mind:

            • You cannot expect elements to stretch to the full width of anything if they have no specified reason to do so. Check the default width value (auto):

            https://developer.mozilla.org/en-US/docs/Web/CSS/width

            • A child cannot normally grow beyond the limitations of its parent, specially by default, auto width on your input and auto width on its div parent...will never lead to 100% width. You ought to be specific.

            EXTRA

            To adjust the content of the .user div based on the size of the content, you can try max-content, which would make your examples look like this:

            Please read this article, it explains in detail max-content, min-content, fit-content, pro's and con's, etc.
